Courtney is a surname originating from England, France and Ireland. In the latter, it is anglicised of the Gaelic Ó Curnáin 'descendant of Curnán' (a diminutive of corn 'horn'), a Munster Irish given name. A variant of Cournane, the name is prevalent in County Kerry. It may also be derived from McCourtney (), or more so, of the former Anglo-Norman origin.
