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