Labour Party (Ireland)

The Labour Party (Irish: Páirtí an Lucht Oibre, lit. 'Party of the Working People') is a centre-left and social democratic political party in the Republic of Ireland. Founded on 28 May 1912 in Clonmel, County Tipperary, by James Connolly, James Larkin, and William O'Brien as the political wing of the Irish Trades Union Congress.

Labour continues to be the political arm of the Irish trade union and labour movement and seeks to represent workers' interests in the Dáil and on a local level. Unlike many other Irish political parties, Labour did not arise as a faction of the original Sinn Féin party, although it merged with the Democratic Left in 1999, a party that traced its origins back to Sinn Féin. The party has served as a partner in coalition governments on eight occasions since its formation: seven times in coalition either with Fine Gael alone or with Fine Gael and other smaller parties, and once with Fianna Fáil. This gives Labour a cumulative total of twenty-five years served as part of a government, the third-longest total of any party in the Republic of Ireland after Fianna Fáil and Fine Gael.

Led by Ivana Bacik, it is the fourth-largest party in Dáil Éireann, with eleven seats, and is the fourth-largest party in Seanad Éireann, with two seats, making Labour the fourth-largest party in the Oireachtas overall as of 2025. It currently has 1 MEP. The Labour Party is a member of the Progressive Alliance, Socialist International, and Party of European Socialists.
