Sir John Coryton, 4th Baronet (c. 1690 – 22 May 1739) was a British landowner and politician who sat in the House of Commons between 1713 and 1734.

Coryton was born at Greenwich, the only son of Sir William Coryton, 3rd Baronet and his wife Susanna Littleton, daughter of Edward Littleton MP of Pillaton, Staffordshire. He was educated at Rugby School from 1698 and matriculated at Christ Church, Oxford on 14 October 1708, aged 18. He succeeded to the baronetcy on the death of his father on 6 December 1711. He married Rachel Helyar, daughter of William Helyar of East Coker, Somerset on 31 October 1715.

Coryton died on 22 May 1739. He had no children and the baronetcy became extinct.
