Culter Fell is a hill in the Culter Hills range, part of the Southern Uplands of Scotland. It is the county top of the historic county of Lanarkshire, as well as the highest point in South Lanarkshire council area. It is the culmination of a network of ridges that lie south of the village of Coulter, close to the town of Biggar. There is an alternative starting point at Glenkirk, to the east (NT077295). From here, a circular route along a ridge including Chapelgill Hill is among several additional options.
