John Ratcliffe or possibly Radcliffe (1700 – 1775) was Master of Pembroke College, Oxford.

Son of clergyman, Robert Ratcliffe, he was educated at John Roysse's Free School in Abingdon, (now Abingdon School).

John Ratcliffe became Master of Pembroke on 23 February 1738.

[1] 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.

[2] He was rector of Coln Rogers (1739–1775) and canon of Gloucester (1739–1775).
