Logan (Scottish Gaelic: An Lagan) is a village in East Ayrshire, southwest Scotland. It is east of Cumnock, by the Lugar Water.
Logan is served by a regular daytime bus service (#49A) to Cumnock operated by Shuttle buses Ltd of Kilwinning. The nearest train station is Auchinleck.
The village provides little industry and mostly serves as a dormitory village for Cumnock and surrounds. The Ayr to Cronberry railway line would have passed behind the village before its closure in the 1960s. The track bed now serves as a popular footpath.
