The Battle of Lough Raska (Irish: Loch Rasca) or Battle of Corcomroe (Irish: Corca Mrua) took place on 15 August 1317 near Corcomroe Abbey in north County Clare, Ireland. It was part of a struggle for power between Clann Briain and Clann Tadhg, rival septs of the O'Brien dynasty, and was also part of the Anglo-Norman wars in Ireland. Forces loyal to Muircheartach Ó Briain were commanded by Diarmait Ó Briain in a pitched battle against Donnchadh Ó Briain, who was an ally of Mathghamhain Ó Briain and Richard de Clare. Both armies were about 9,000 men each. Diarmait Ó Briain's forces were victorious. This would be a precursor to the Battle of Dysert O'Dea.
