Trinity Gaels is a Gaelic Athletic Association club based in Donaghmede in Dublin, Ireland. Trinity Gaels were founded in 1975 to cater for the growing population in the Donaghmede area. The club got their name from the local Roman Catholic parish name, the parish of the Holy Trinity. Gaels won the Dublin Intermediate Football Championship in 1994 and therefore qualified to senior status.

For the past few seasons Gaels have been playing in Division 1 of the league. Trinity Gaels played in Fr Collins Park, Hole in the Wall Road, until the middle of the 2006 season when they moved to new purpose built grounds including clubhouse and floodlit pitches on Drumnigh Road. A book entitled "Trinity Gaels – a look back through the last years", was launched at the Hilton Hotel, Malahide Road on 15 January 2007 to celebrate 30 years of the club's existence.
