John Evans (4 July 1756 – October 1846) was a Welsh surgeon and cartographer.
Evans was born on 4 July 1756 at Llwyn-y-groes, Llanymynech on the border between Montgomeryshire, Wales and Shropshire, England.
He obtained degrees of Bachelor of Arts (1778), Master of Arts (1779) and Bachelor of Divinity (1783) from St Alban Hall, Oxford, before obtaining the degree of Doctor of Medicine from the University of Edinburgh.

One of his sons was Robert Wilson Evans, who became Fellow and tutor of Trinity College, Cambridge and archdeacon of Westmorland, and it was at this son's house in Heversham that Evans died in October 1846 aged 90.
