Cumnock (Cumnag in Gaelic) is a town in East Ayrshire, Scotland. The town sits at the confluence of the Glaisnock Water and the Lugar Water. There are three neighbouring housing projects which lie just outside the town boundaries, Netherthird, Craigens and Logan, with the former ironworks settlement of Lugar also just outside the town, contributing to a population of around 13,000 in the immediate locale. A new housing development, Knockroon, was granted planning permission on 9 Dec, 2009 by East Ayrshire Council.
