The midcoast area of Maine was inhabited by coastal and woodland Native Americans such as the Abenaki (or Wabanaki) until they were mostly dislocated by Europeans beginning in the 17th century.

The first European (English) people moved into the area in and around Liberty in the late 18th century. The first settlement was then known as Davistown Plantation, which is incorporated into neighboring Montville in the early 19th century. Mills in Liberty produced materials that were used in the shipbuilding industry that thrived in nearby coastal towns, such as Waldoboro, during the early 19th century.

In 1827, Liberty separated from Montville and was incorporated as a town.

The middle to late 19th century saw a decline in population and goods produced. This correlates with the decline of the shipbuilding industry.

According to the United States Census Bureau, the town has a total area of 28.40 square miles (73.56 km), of which 26.00 sq mi (67.34 km) is land and 2.40 sq mi (6.22 km) is water. The largest water body in the town is St. George Lake. Other bodies of water include: Stevens Pond (339 acres (137 ha)), Trues Pon (173 acres (70 ha)), Little Pond (69 acres (28 ha)), Cargill Pond (57 acres (23 ha)) and Colby Pond (26 acres (11 ha)). Liberty is served by Maine State Routes 3, 220, and 173. It is bordered on the north by Montville, on the east by Searsmont, on the southeast by Appleton, on the southwest by Washington and on the west by Palermo.

Liberty is home to Lake St. George State Park.
