Castlemagner GAA is a Gaelic Athletic Association club based in the village of Castlemagner in the north-west of County Cork, Ireland.

Founded in 1900, the club plays both hurling and Gaelic football and is affiliated with Duhallow GAA.

[citation needed] At under age level, the Castlemagner club amalgamates with Kilbrin as Croke Rovers - as neither club have been able to field an underage team on their own.

Ladies' Gaelic football and camogie are also played within the club.
