St John's is a Gaelic Athletic Association club based in Carraroe and the eastern ward of Sligo, Ireland.

It is one of the newer clubs in the county, having been formed in 1987 after a re-organisation of the GAA structures in the Sligo urban area.

[1] In 2013, St John's seniors won ten games out of a possible eleven and contested the Division One League final for the very first time in their short history against Tourlestrane but lost.

Currently the club fields Senior, Intermediate and Junior A teams and traditionally draws its players from Carraroe, Cairns Hill, Cranmore, Garavogue and Mail Coach Road which are predominantly areas from Sligo town.

It is the first non-smoking club in Sligo, leading to chairman Seamus Casey being presented with an award by Dublin player Brian Fenton at Croke Park.
