The South Devon Militia was a part-time military unit in the maritime county of Devonshire in the West of England. The Militia had always been important in the county, which was vulnerable to invasion, and from its formal creation in 1758 the regiment served in home defence in all of Britain's major wars, later as a reserve battalion for the Devonshire Regiment. It was disbanded in 1908.
