Georgetown is a town in Sagadahoc County, incorporated on June 13, 1716 from a portion of Arrowsic Island. In 1738 it annexed Parker's Island, and followed with Small Point in 1741. Later it set off land to form three area towns: Bath (1781), Phippsburg (1814), and Arrowsic (1841).
Settled in the early 1600's, it shares its early history with nearby Phippsburg and Arrowsic.
Georgetown is home to Reid State Park and to the former summer residence of sculptor William and artist Marguerite Zorach. Their daughter Dahlov Ipcar made it her home as well.
Josephine Newman Sanctuary, managed by the Maine Audubon Society, has two miles of trails through salt marsh and stands of red oak, white pine, spruce, and hemlock beside rocky shore of Robinhood Cove. Ledgewood is a nature preserve, managed by the Nature Conservancy, of over a mile of spruce-fir forest, granite shore and moss-lichen understory. .
Located on Georgetown Island, its southern tip is bounded by Sheepscot Bay to the East and the Kennebec River to the west. Maine Route 127 south from Woolwich, ends at Five Islands with its beach and harbor on Sheepscot Bay, near the south end of the Little Sheepscot River, which is not so much a river as a waterway from the Sasanoa River to Five Islands.
