John Smyth or Smith (1744–1809) was a clergyman and Master of Pembroke College, Oxford.

John Smyth became Master of Pembroke in 1796.

[1][2] The close relationship between Abingdon School and Pembroke College resulted in seven Old Abingdonians being appointed as consecutive masters at Pembroke between 1710 and 1843.

They were Colwell Brickenden 1709–1714; Matthew Panting, 1714–1738; John Ratcliffe, 1738–1775; William Adams, 1775–1789; William Sergrove 1789–1796; John Smyth 1796–1809; and George William Hall, 1809–1843.

[3] He was rector of Coln Rogers (1799), curate of Eastleach-Turville, rector of Rudford (1801), vicar of Fairford (1804) and canon of Gloucester (1796–1809).
