William Goodwin (d. March 11, 1673) was a founder of Hartford, Connecticut.
Goodwin was born in England and sailed from London in the ship Lion to New England on September 16, 1632. He immediately settled in the part of Cambridge, Massachusetts that is now Newton. In 1635-36, he was one of the company which removed to Connecticut and settled in Hartford. His home lot was on Main Street, extending from Wadsworth Street to Arch Street. He purchased large tracts of land up the Connecticut River, and was one of the agents of the town employed to purchase Farmington from the Native Americans. In 1659, he and a number of Hartford people settled Hadley, Massachusetts. In anticipation of his return to Connecticut, he sold some of his Hadley lands in January 1669, his wife Susanna - possibly the widow of Thomas Hooker - joining the deed. It was the first record of his wife in America.
Goodwin died on March 11, 1673.
Goodwin married a woman named Susanna.
