Westport is a town in Bristol County, Massachusetts, United States. The village of North Westport lies in the town. There were several cotton mills along the river, the largest of which was at the junction of the river with Lake Noquochoke on the Dartmouth town line. The Macomber turnip traces its ancestry to turnips sowed in Westport shortly after 1876. During the Second World War, a coastal defense installation was raised on Gooseberry Neck. The town is now mostly residential, with a large farming community. Horseneck Beach State Reservation, located to the north and west of Gooseberry Neck, is a popular summer destination for many in the area.
