Athleague () 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. The village is in a townland and civil parish of the same name. As of the 2022 census, the village population was 296. The village is 8 km south-west of Roscommon town, at the junction of the N63 national route and the R362 regional road. The R357 leaves the N63 south of the village. The town has a mill and a restored church. The church is the local parish for the surrounding towns.
Athleague's English name is derived from the Irish ÃÂth Liag, meaning 'the ford of the flagstones', which indicates its use as a crossing point between the kingdoms of the UàMaine and UàBriúin.
Athleague's church was founded sometime around 500 by Maenucan Atha Liacc ('Maonagán of Athleague').
The area is mentioned a number of times in the Annals of Connacht, the Annals of Lough Cé and the Annals of the Four Masters. According to the Annals of Inisfallen, in the late 10th century ("AI993.2"), Brian Boru under took a "naval raid" in the area "he reached Breifne from Loch Ràby way of ÃÂth Liac northwards".
