Colquhoun (/kəˈhuːn/ kə-HOON) is a surname of Scottish origin.^[1] It is a habitational name from the barony of Colquhoun in Dunbartonshire.^[1] The Scottish Clan Colquhoun originated there. The name is possibly derived from the Gaelic elements còil ("nook"), cùil ("corner"), or coill(e) ("wood") + cumhann ("narrow"), or comh-thonn ("wave crash").^[2] The "l" is typically silent per developments in the Scots language.

Phonetically, MacOlquhoun is similar to MacElhone/MacIlhone and therefore Colquhoun may sometimes derive from the name the Gaelic name Mac Giolla Còmhghan.^[3] Còmhghan is derived from comh ("together") and gan-, gen- ("born").^[4]
