John Westley (1636–1678) was an English nonconformist minister. John Wesly (his own spelling), Westley, or Wesley was probably born at Bridport, although some authorities claim he was born in Devon, the son of the Rev. Bartholomew Westley and Ann Colley, daughter of Sir Henry Colley of Carbery Castle. He was educated at Dorchester Grammar School and as a student of New Inn Hall, Oxford, where he matriculated on 23 April 1651, and graduated B.A. on 23 January 1655, and M.A. on 4 July 1657. After his appointment as an evangelist, he preached at Melcombe Regis, Radipole, and other areas in Dorset. Never episcopally ordained, he became Vicar of Winterborne Whitechurch in 1658.
