Dailly is a village in South Ayrshire, Scotland. It is located on the Water of Girvan, five miles south of Maybole, and three miles east of Old Dailly. "New Dailly", as it was originally known, was laid out in the 1760s as a coal-mining village. In 1849 a fire broke out in Maxwell Colliery, one of the nearby mines, and continued to burn for 50 years. In Dailly there are two castles which the locals call the new castle and the old castle; they are both derelict.
