County Louth is a former parliamentary constituency in Ireland, which was represented in the House of Commons of the Parliament of the United Kingdom. It returned two Members of Parliament (MPs) from 1801 to 1885, and one MP from 1918 to 1922.
From 1801 to 1885, the constituency comprised County Louth, except for the parliamentary boroughs of Drogheda and Dundalk. It succeeded the constituency of County Louth in the Irish House of Commons. Between 1885 and 1918 the county was divided into the county divisions of North Louth and South Louth. In 1918, the reunited constituency covered the entire county of Louth plus a small part of County Meath near Drogheda.
At the 1918 general election, Sinn Féin won by 255 votes, its narrowest margin of victory in that election. John J. O'Kelly, a native of County Kerry, resident in Glasnevin, Dublin, was Louth's first TD. The constituency was merged with Meath to form the 5-seat LouthâÂÂMeath constituency for the 2nd and 3rd Dála.
