Athleague (Irish: Áth Liag (na Sioca), meaning 'ford of the flagstones') is a village and a parish in the Diocese of Elphin on the River Suck in the west of Ireland in County Roscommon, near the town of Roscommon. Its church was founded sometime around 500 by Maenucan Atha Liacc ('Maonagán of Athleague'). The name is derived from Áth Liag ('the ford of the flagstones'), indicating its use as a crossing point between the kingdoms of the Uí Maine and Uí Briúin.
