St Mary's College Rugby Football Club is a rugby union club based in South Dublin, Ireland, playing in Division 1A of the All-Ireland League. The club was founded in 1900 by former pupils of St. Mary's College, Dublin and was originally known as Old St Mary's. The club won the Leinster Senior Cup for the first time in 1958. In 2000 they won the AIB League for the first time under the captaincy of Trevor Brennan.
The club was formerly sited at College Drive, Templeogue from 1955 until the 1970s, including clubhouse and grounds which have since been developed as Fortfield Square apartments. In the 1970s, the club moved to Templeville Road to rugby grounds formerly owned and used by Templeogue College, the Holy Ghost Fathers sister school of St Mary's College.
