The title of Earl of Devon was created several times in the Peerage of England, and was possessed first by the de Reviers family, and later for the Courtenay. It is not to be confused with the titles of Earl of Duke of Devonshire, held by the Cavendish family, although the patent for the creation of those peerages used the same Latin words, Comes Devon. The title was dormant for several centuries after the death of the last Earl in 1556, but a Courtenay successfully claimed the title in the mid-19th century.
Unlike the Dukes of Devonshire, the Earls of Devon are strongly connected with the county of Devon. Their seat is Powderham Castle, near Starcross on the River Exe.
