Borris-in-Ossory GAA is a Gaelic Athletic Association club in the village of Borris-in-Ossory, County Laois, Ireland.
The club colours are red and white and the club grounds are called O'Keefe Park.
Formerly, primarily a hurling club, Borris-in-Ossory now operates solely as a gaelic football club.
It amalgamates at all age levels with its neighbouring club, Kilcotton GAA, with which it competes in hurling as Borris-in-Ossory–Kilcotton GAA.
The clubs however field separate Gaelic football teams, and compete as separate clubs in the Laois Junior C Football Championship.
The club won five Laois Senior Hurling Championships, the last of which came in 1972. The Laois and Leinster hurler Christy O'Brien played in all five wins and was captain for the first four wins between 1956 and 1961.
