John Hill (c. 1589–1657) of Dorchester was an English merchant and politician who sat in the House of Commons from 1628 to 1629.
Later he replaced John Yeate as an Alderman of Dorchester and a week later was appointed a Capital Burgess.
In 1643, when Dorchester was threatened by the Royalists, Hill and other merchants in the town tried to send their goods to safety by ship from Weymouth, but it was captured.
Nevertheless, the war presented opportunities to make money and among other things he sold provisions to the besiegers of Sherborne.
He left £100 for an endowment known as the Hill Exhibition to support a poor scholar from Dorchester at one of the universities.
