Dundalk Young Irelands GFC is a GAA club from Dundalk, County Louth, which fields Gaelic football teams in competitions organised by the Louth county board.
The club was formed in the same year as the Gaelic Athletic Association, making it the oldest club in Louth and one of the oldest in Ireland. 
 

Players have traditionally come from the Seatown area of central Dundalk close to where the St. Mary's College grounds – the club's home pitch for several decades – are located.

Dundalk Gaels (formed in 1928) were the Irelanders' main rivals for many years. Between 1940 and 1952, the two clubs won eight out of thirteen Louth senior championship titles. Town neighbours Seán O'Mahony's and Clan na Gael have provided local opposition at the intermediate grade in recent years.
