Anson is a town in Somerset County, Maine, United States.

The land upon which Anson was founded was historically home to the Norridgewock Abenaki.

General Benedict Arnold and his troops passed through Anson village in 1775 on their way up the Kennebec River to the ill-fated Battle of Quebec.

Water power sites around the Carrabassett River helped North Anson develop into a small mill town.

By 1876, North Anson had become the northern terminus of the Somerset Railroad, which began at Oakland in 1872.

[5] As of June 14, 2007, the abandoned Pan Am Railways spur was reopened, and the first train ran the length of the line for the first time in twenty years.

On November 30, 2021, it was announced that the State of Maine had acquired the former rail line for conversion into a multi-use rail trail, as part of a larger project to create a trail from Oakland to Embden.

It borders the towns of Starks to the south, Industry and New Vineyard to the west, New Portland and Embden to the north, and (across the Kennebec River) Madison to the east.
