Colin Og Campbell of Lochawe

Sir Colin Og Campbell of Lochawe (died 1340) was the eldest son of Sir Neil Campbell and stepson of Mary Bruce, sister of Robert the Bruce. In 1316 the king granted him Lochawe and Ardscotnish as a free barony, in return for troops and a forty-oared galley when required.

He campaigned with Bruce in Ireland in 1315–1318 and later supported David II against Edward Balliol. By his wife Helena he left a son Archibald, ancestor of the Earls of Argyll.
