Georgetown is a town in Sagadahoc County, Maine, United States.

[2] Home to Reid State Park, the town is part of the Portland–South Portland–Biddeford, Maine Metropolitan Statistical Area.

Abenaki Indians called the island Erascohegan, possibly meaning "good spear-fishing."

The town of Newtown-on-Arrowsic was rebuilt in 1714 on the southern end of Arrowsic Island, which was incorporated in 1716 by the Massachusetts General Court as Georgetown-on-Arrowsic, named for Fort St. George.

[5] About half of Parker's Island provided grazing land, and some residents raised livestock and produced butter and cheese.

By 1841, all the other parts of Georgetown had been set off and incorporated as towns, leaving Parker's Island with sole claim to the ancient name.

Situated between the mouths of the Sheepscot and Kennebec rivers on the Gulf of Maine, Georgetown developed into a summer resort, attracting a number of prominent artists.

[1] Georgetown is located on an island near the mouth of the Kennebec River and Gulf of Maine, part of the Atlantic Ocean.

The island is separated by water from Westport to the northeast, Southport to the east, Phippsburg to the west, Arrowsic to the northwest, and Woolwich to the north.

29.9% of all households were made up of individuals, and 11.3% had someone living alone who was 65 years of age or older.
