Hanover is a town in Plymouth County, Massachusetts, United States. The population was 13,879 at the 2010 census.
The area of Hanover was first settled by English settlers in 1649 when William Barstow, a farmer, built a bridge along the North River at what is now Washington Street. The land was the westernmost portion of the town of Scituate, and it would officially separate and be incorporated as a town June 14, 1727. The name “Hanover” is probably a tribute to King George I, the first Hanoverian King of Great Britain. (While George I died on June 11, 1727, the reports would not have reached the colonies until after the town’s incorporation.) Hanover’s early industry revolved around farming, small mills and a shipbuilding area along the North River.
