Seoul has been holding public St. Patrick’s Day festivals for a quarter of a century. The first official parade took place on March 17, 2001, organized by the Irish Association of Korea with support from the Irish Embassy. Earlier Irish community celebrations had been held in South Korea from 1976, but 2001 marked the point when St. Patrick’s Day moved into the streets of Seoul as a public cultural event.
The festival subsequently became one of the largest foreign cultural celebrations in the Korean capital. An estimated 18,000 people attended in 2008, while the 2011 event attracted more than 10,000. At different times the parade has occupied some of central Seoul’s best-known public spaces, including Daehangno, Cheonggyecheon and Insadong, before the festival settled for long periods at D-Cube City Plaza in Sindorim.
The 2026 St. Patrick’s Day Festival was held on Saturday, March 14 at D-Cube City Plaza, under the theme “Seoul’s Going Green.” The programme mixed Irish traditional music and dance with Korean performers and contemporary Irish culture. One of the performers, Gan Ainm, was particularly representative of what the festival has become: an Irish traditional music group composed entirely of Korean musicians.
That Korean participation is central to the event. South Korea has only about 900–1,000 resident Irish citizens, nowhere near enough to produce a large diaspora festival on its own. The audience, performers and volunteers have consequently always included large numbers of Koreans.
The festival today
Seoul’s present St. Patrick’s Day celebration is better described as an Irish cultural festival with a parade tradition than as a huge conventional street parade.
The main event combines live music, Irish dancing, opportunities for the crowd to join céilí dancing, costumes and Irish cultural displays. Gaelic football has appeared in the programme, and Irish and Korean musicians perform alongside one another.
In years when the festival has occupied a suitable central location, a procession has formed an important part of the day. In other years the emphasis has been on the stage programme rather than a long parade route.
That has been true particularly at D-Cube City Plaza, immediately outside Sindorim Station in southwestern Seoul. It lacks the visual impact of the earlier Cheonggyecheon route but provides a practical space for a large open-air concert.
The 2026 festival returned there on March 14. The programme demonstrated how thoroughly Irish culture has acquired Korean practitioners. Gan Ainm's musicians play fiddle, concertina, banjo, guitar and traditional Irish repertoire; some have been involved with the Korean Irish-music scene for more than a decade.
For a visitor, that is probably the most interesting feature of St. Patrick’s Day in Seoul. This is not simply several hundred Irish expatriates celebrating among themselves. Much of the music, dancing and organization now involves Koreans who have developed their own interest in Irish culture.
Ireland and Korea before St. Patrick’s Day
The Irish presence in Korea long predates the modern festival.
Its strongest early connections came through missionaries and the Korean War rather than mass migration.
Irish Catholic missionaries became particularly important during the twentieth century. The Missionary Society of St Columban, founded in Ireland in 1918, sent missionaries to Korea from the 1930s. Irish religious subsequently worked in parishes, hospitals, education and social services.
Ireland’s government describes the Columban missionaries and the Hospitaller Order of St John of God as central to the long relationship between Ireland and Korea. Their work extended into healthcare, disability services, mental-health care and education.
This created an Irish presence quite unlike that of the great nineteenth-century diaspora cities. There was no Irish neighbourhood in Seoul and no mass migration of Irish labourers. The Irish people most visible in twentieth-century Korea were often priests, brothers, nuns and other religious workers.
Then came the Korean War.
Irishmen in the Korean War
Ireland did not send a national military contingent to the Korean War of 1950–53. The Republic of Ireland had not yet joined the United Nations when the war began.
Irishmen nevertheless fought in substantial numbers under other flags.
Some served in American, Canadian, Australian and other forces. The most identifiable Irish formation was the British Army’s Royal Ulster Rifles, whose soldiers came from both parts of Ireland.
The regiment suffered heavily during the fighting around Happy Valley in January 1951, during the Chinese offensive south of Seoul.
Irish missionaries were caught in the conflict as well.
The Irish connection with the war later became part of the public Irish presence in Seoul. In 2010, the St. Patrick’s Day programme explicitly commemorated Irish people who had died while serving with United Nations forces in Korea, and organizers collected donations towards an Irish Korean War memorial.
That memorial was eventually unveiled at the War Memorial of Korea in Seoul in 2013, commemorating Irishmen who fought and died in the conflict.
The Korean War therefore provides an important historical layer beneath what might otherwise appear to be a very recent expatriate festival.
An Irish community emerges
South Korea's transformation after the war gradually produced a different Irish population.
Teachers, businesspeople, engineers and other professionals joined the missionaries. English-language teaching became an especially common route into Korea for younger Irish migrants.
Formal diplomatic relations between Ireland and the Republic of Korea were established in 1983.
Political and economic ties expanded thereafter, but the Irish community remained small. Even today only about 900–1,000 Irish citizens are resident in Korea at any particular time.
The community nevertheless began organizing well before the modern St. Patrick’s Day parade.
The official Seoul tourism authority dates St. Patrick’s Day celebrations in South Korea to 1976. These early events were community celebrations rather than the large public festival that exists today.
During the early 1990s a loose Korea Irish Association was active. The organization that became the Irish Association of Korea traces its roots to this period.
A more formal structure followed.
The Irish Association of Korea
The Irish Association of Korea, or IAK, dates its establishment to 1996.
Its origins lay in an event called the St. Patrick’s Charity Ball. The ball became an established part of the community calendar and developed alongside a St. Patrick’s Festival Hooley involving music, dancing, food and drink.
The association's purpose was broader than organizing events for Irish expatriates.
From the beginning it sought to introduce Irish culture to Koreans and other nationalities. It organized music nights, film screenings, poetry and book readings, quizzes, social gatherings and performances by visiting Irish artists.
That outward-looking approach proved important when the association decided to create a public St. Patrick’s Day parade.
The inspiration also had a connection with Tokyo.
Irish expatriate organizations across East Asia were increasingly communicating with one another during the 1990s. Tokyo had demonstrated after 1992 that a St. Patrick’s Day procession could attract a large local audience even where the resident Irish population was tiny.
Seoul followed at the beginning of the next decade.
March 17, 2001: Seoul’s first parade
The first official St. Patrick’s Day Parade in Seoul took place on March 17, 2001.
The Irish Embassy was directly involved.
According to the Irish Association of Korea, embassy official Peter Ryan recruited Irishman Des Scully and American expatriate Tom Coyner to help stage the event. Coyner subsequently became closely involved with the Irish community organization.
From then on, the parade and the existing festival-hooley tradition were organized together.
The first parade established a sequence that has continued, in changing forms, for 25 years.
Unlike the older Irish parades of North America and Australasia, there was no Catholic school system or Hibernian network to provide thousands of marchers. Organizers instead recruited expatriates, Korean cultural groups, musicians, dancers and members of the public.
That made Seoul's St. Patrick’s Day culturally mixed almost from the beginning.
Growth during the 2000s
The festival expanded rapidly.
By the middle of the decade, surviving photographs show sizeable street processions and outdoor performances. The Irish Association's archive preserves records of festivals in 2005, 2006, 2007, 2008 and 2009.
Attendance grew well beyond the Irish community.
The breakthrough appears to have come during the late 2000s. The IAK estimated attendance at the 2008 festival at 18,000.
That figure made St. Patrick’s Day one of Seoul's largest foreign-community festivals.
The formula combined a street procession with a free open-air concert and cultural fair. Traditional Irish musicians and dancers appeared alongside Korean groups, rock bands and other international performers.
Koreans were increasingly participants rather than simply spectators.
This was exactly what the association wanted. Its stated objective was not merely to provide Irish expatriates with a national-day celebration but to use the occasion to introduce Irish culture to Korea.
By 2010, the event had become sufficiently established for organizers to call it Seoul’s 10th Irish Festival.
Cheonggyecheon in 2010
The 2010 festival provides one of the best records of Seoul's parade at its height.
It took place at Cheonggye Plaza on March 20.
The restored Cheonggyecheon stream runs through central Seoul, and its redevelopment had created a long public space ideally suited to a procession.
The festival opened with an Irish cultural exhibition and performances before the parade began at 2 p.m.
Irish ambassador Eamonn McGee formally opened the event. A bagpiper led the procession, which included amateur and professional marching groups and members of the general public. The route ran along streets parallel to Cheonggyecheon before returning to the plaza.
The day's entertainment mixed Irish and Korean culture. Traditional Irish musicians and step dancers performed alongside Korean university bands, Korean folk performers and a Korean U2 tribute band. Crowd participation in Irish folk dancing had already become a regular feature.
The organizers also used the festival to remember Irish involvement in the Korean War.
And Seoul acquired another St. Patrick’s Day tradition that year.
Namsan Tower turns green
For the 2010 festival, N Seoul Tower on Namsan was illuminated green.
The Irish Association explicitly linked the illumination to the emerging international practice of turning famous landmarks green for St. Patrick’s Day. The tower remained green from March 17 through March 20.
For Seoul, this was an unusually effective symbol.
Namsan Tower is visible across large areas of the capital. Illuminating it green gave St. Patrick’s Day a citywide visibility that a small expatriate community could never have achieved through numbers alone.
The practice also connected Seoul to Ireland's expanding international St. Patrick’s Day promotion.
The festival itself was becoming equally visible.
Insadong and the 2011 festival
The following year the celebration moved to Insadong, the central Seoul district known for traditional Korean culture, galleries and crafts.
The 11th St. Patrick’s Festival took place there on March 19, 2011.
The location changed the feel of the event.
Rather than occupying a modern plaza, the Irish festival was now embedded in an area already associated with Korean traditional culture. Irish musicians and dancers performed for a predominantly local audience alongside other Seoul cultural activity.
The IAK reported that previous festivals had attracted more than 15,000 spectators.
The open-air concert was by then the centrepiece. Irish musicians living in Korea performed alongside visitors from Ireland, while the audience was invited to join folk dances.
The participation of the United States Eighth Army Band, performing Irish music, also reflected the international character of the event.
Seoul's St. Patrick’s Day had become much more than a gathering of Irish citizens.
The move to Sindorim
During the 2010s the festival increasingly became associated with D-Cube City at Sindorim.
The 2012 festival brought thousands to D-Cube, and by 2014 organizers were describing the event there as the 14th annual St. Patrick’s Day Festival.
The format emphasized performances.
The 2014 festival ran from noon until 6 p.m. and featured traditional Irish music, rock music and dancing by performers from Korea and overseas. Organizers said the open-air concert had attracted as many as 10,000 spectators in previous years.
Sindorim was less picturesque than Insadong or Cheonggyecheon, but it had practical advantages. D-Cube Plaza offered a contained outdoor venue beside one of Seoul's busiest transport interchanges.
The festival could attract people who had no previous connection with Ireland simply because they encountered it while moving through the city.
It also increasingly emphasized cultural participation rather than watching a formal procession.
Irish culture takes root in Korea
By this stage, Seoul had developed something that the organizers of the 2001 parade could not simply have imported: a Korean community actively practising Irish culture.
Irish traditional music sessions developed in the city.
Korean musicians learned fiddle, tin whistle, concertina and other instruments. Irish dance attracted Korean students. Gaelic football developed through the Seoul Gaels, including eventually a children's programme.
Irish literature found a particularly receptive audience.
Korea has active organizations devoted to James Joyce and W. B. Yeats, while Irish literature, music, dance and even the Irish language form part of the broader cultural relationship between the countries.
The St. Patrick’s Day stage consequently changed.
Where organizers once needed to bring professional performers from Ireland to provide authentic traditional music and dance, Korean performers increasingly supplied it themselves.
That development is particularly visible in 2026.
Gan Ainm and a Korean Irish-music scene
Among the acts appearing at the 2026 festival was Gan Ainm.
All four members are Korean.
The group includes banjo player Darren Choi, fiddler Koh Hae-young, concertina player Koh Seulki, and singer and guitarist Zee.
Choi became involved with Irish traditional music in Seoul after attending a session and joining musicians already playing the repertoire. By 2026, Gan Ainm could appear at Seoul's principal Irish festival as an entirely Korean Irish traditional band.
This is probably the clearest evidence of how the festival has changed.
The first parade needed an Irish embassy official and expatriate volunteers to create an Irish event for Seoul.
Twenty-five years later, Korean musicians were playing Irish traditional music for it.
The wider Irish community
The Irish Association remains at the centre of this activity.
Its membership and events now bring together Irish citizens, Koreans and people of other nationalities. The association estimates the resident Irish population of Korea at roughly 900–1,000 at any one time.
Its activities extend well beyond March.
Bloomsday is celebrated in Seoul; in 2026, the IAK and Joyce Society organized a June 16 programme devoted to Ulysses and Joyce's relationship with Nora Barnacle.
The association also organizes the Solas sunrise walk, a mental-health initiative that by 2026 was being held simultaneously in Seoul, Busan, Jeju and Jeonju. More than 200 people participated that year.
This broader programme helps explain why St. Patrick’s Day has survived. It is supported by an active year-round Irish-Korean cultural network rather than an organization that exists solely to mount a parade.
Ireland and Korea today
Official relations have expanded alongside the community connection.
Ireland and South Korea established diplomatic relations in 1983. Bilateral trade now exceeds €5 billion annually.
The Irish Embassy in Seoul supports cultural activities as well as diplomatic and commercial relations. Irish ministers regularly visit Korea during St. Patrick’s week.
In 2024, for example, Minister of State Ossian Smyth attended the Seoul festival and visited the War Memorial of Korea, where he paid respects to those who died in the Korean War, including Irishmen and people of Irish descent.
The annual festival has therefore become both a community event and one of Ireland's most visible pieces of public diplomacy in Korea.
But its popularity cannot be explained by official support alone.
The festival survived because Koreans attended it, performed at it and eventually helped organize and sustain the Irish cultural activities behind it.
Seoul in 2026
The 2026 St. Patrick’s Day Festival took place at D-Cube City Plaza on Saturday, March 14, celebrating the public tradition that began with the first parade in 2001. Its theme was “Seoul’s Going Green.”
The event remains relatively modest compared with the giant Irish-American parades, and even within Asia Tokyo offers a more impressive conventional street procession.
Seoul is nevertheless one of the strongest St. Patrick’s Day localities in Asia.
Its history has several distinct layers. Irish missionaries established connections with Korea decades before formal diplomatic relations. Irishmen fought and died in the Korean War. Community St. Patrick’s celebrations are recorded from 1976. The Irish Association developed from the expatriate organizations of the early 1990s and was formally established in 1996. The first public parade followed on March 17, 2001.
The event then grew remarkably quickly. By 2008, organizers estimated attendance at 18,000. In 2010 a full street procession marched beside Cheonggyecheon while Namsan Tower glowed green above Seoul. The festival subsequently moved through Insadong and Sindorim while its emphasis shifted increasingly towards music, dancing and cultural participation.
The strongest measure of its success is no longer crowd size. It is that Irish culture has acquired practitioners in Korea itself.
In 2001, a small foreign community had to create Seoul's first St. Patrick’s Day parade. In 2026, Korean musicians playing fiddle, concertina and banjo could take the stage at the same festival and perform Irish traditional music for a Korean crowd.
