The clubhouse is situated beside
Marlay Park just off the Ballinteer bypass and junction 13 on the M50. It was founded in May 1982. Initially the chosen name was Ballinteer Gaels though the name was later changed to Ballinteer St Johns. The club's crest is made up of Three Castles (Dublin crest), The Eagle (Emblem of St John the Evangelist) and the
Celtic Cross (GAA emblem). A large clubhouse,
Áras Naomh Eoin, was opened in 2003. In December 2020, former
Laois inter-county footballer
Seán Dempsey was named as
manager of the club's team competing in the
Dublin Senior Football Championship. ==Notable players==
