Robert Taft (born c. 1640 - 8 February 1725) was the founder of the prominent Taft family in the United States.
He moved to Mendon in 1679 where he secured many grants of land, including Mendon pond. The pond was often called Taft's pond as they owned all the land around it. In 1680 he became one of the first selectmen of Mendon and served as constable in 1695 and 1697. Robert Taft was appointed to a number of committees, which included "to take care that the minister's house be done by Dec. 25." and "to view the streams of the town and select a place for a corn mill." His most noted achievement came in 1709 when he and his sons built a bridge over the Blackstone River.
He is a member of the Inter-American Dialogue.
