St Rynagh's (Irish: Naomh Raghnach) is the name of two Gaelic Athletic Association sister clubs that encompass the towns of Cloghan and Banagher in County Offaly, in Ireland.

Formed in 1961, to represent the parish of Cloghan and Banagher, the club gained almost immediate success - winning the senior hurling championship in 1965.

St Rynagh's has also supplied three of Offaly's four All-Ireland Hurling Championship winning captains, namely Padraig Horan, Martin Hanamy and Hubert Rigney.

Other noted players in the club's history include RTÉ pundit Michael Duignan, Pad Joe Whelahan, Aidan Fogarty and Declan Fogarty, David Hughes, Tom and Mícheál Conneely, and first ever all-star goalkeeper Damien Martin.

St Rynagh's have won the Minor, Under 16, and Under 14 Offaly championships in 2007, while also reaching the Semi-Final at the 2007 Féile na nGael in Kilkenny.
