The Taunton River, historically also called the Taunton Great River, is a river in southeastern Massachusetts in the United States. It arises from the confluence of the Town River and Matfield River, in the town of Bridgewater. From there it meanders through the towns of Halifax, Middleborough and Raynham, through the city of Taunton for which it is named, the towns of Berkley, Dighton, Somerset, and the Assonet section of Freetown, to Fall River where it joins Mount Hope Bay, an arm of Narragansett Bay.
