The Battle of Renfrew was fought between the Kingdom of the Isles and the Kingdom of Scotland in 1164, near Renfrew, Scotland. The men of the Isles, accompanied by forces from the Kingdom of Dublin, were commanded by Somairle mac Gilla Brigte, King of the Isles. The identity of the Scottish commander is unrecorded and unknown. Herbert, Bishop of Glasgow, Baldwin, Sheriff of Lanark/Clydesdale, and Walter fitz Alan, Steward of Scotland are all possible candidates for this position. The battle was a disaster for the Islesmen and Dubliners. Somairle was slain in the encounter, apparently by local levies, and his forces were routed.
