Richard Dummer (c.1589—14 December 1679) was an early settler in New England.
He made his fortune as a trader, operating in the port of Southampton, England. He was a Puritan, which at times was contrary to the Established Church and the monarch. He emigrated to the Massachusetts Bay Colony, becoming a founding father there, setting up a stock company, acquiring estates, and establishing a milling business. His eldest son was slain by Indians. Another of his sons was the first American-born silversmith. His grandson William was Governor of the Province of Massachusetts Bay and instrumental in bringing to an end the Indian Wars, and bequeathed his estates to trustees for the establishment of what became the Governor Dummer Academy, the first school of its kind in the province.
