John Forster Charlton (1915–89), was an English traditional musician, originally from near Hexham, Northumberland, who later settled in Gateshead. He at first played fiddle, but later also took up the Northumbrian smallpipes. He was a major figure in the folk music revival during the 1950s and 1960s, and an active member of the Northumbrian Pipers' Society. He was a founder member of the High Level Ranters, playing fiddle and smallpipes on their first record, Northumberland for Ever, but he subsequently left the group. Later he played in a country dance band, The Borderers.
