Lisbon is a town in Androscoggin County, Maine, United States. The population was 9,711 at the 2020 census. It is included in both the Lewiston-Auburn, Maine metropolitan statistical area and the Lewiston–Auburn, Maine Metropolitan New England city and town area. The town of Lisbon includes the villages of Lisbon and Lisbon Falls.

The community was originally part of Bowdoin, a township within the Kennebec Purchase. But because travel to attend town meetings was difficult, on June 22, 1799, the General Court of Massachusetts divided Bowdoin in two to create Thompsonborough. Residents, however, soon grew dissatisfied with the long name. Consequently, it would be renamed in 1802 as Lisbon, after Lisbon in Portugal. In 1808, Lisbon annexed the remainder of Little River Plantation (part of the Pejepscot Purchase) as Lisbon Falls. In 1840, part of Lisbon was set off as Webster.

With fertile and easily cultivated soil, farming was an early industry. Sawmills and gristmills were built using water power from the streams. Larger brick mills followed to manufacture textiles. In 1864, the Worumbo Mill was established to produce woolens, and would remain a principal employer until it burned in 1987.

According to the United States Census Bureau, the town has a total area of 23.82 square miles (61.69 km), of which 22.82 square miles (59.10 km) is land and 1.00 square mile (2.59 km) is water. Lisbon is drained by the Sabattus River, Little River and Androscoggin River.
