Andover is a town in Oxford County, Maine, United States. The population was 752 at the 2020 census. Set among mountains and crossed by the Appalachian Trail, Andover is home to the Lovejoy Covered Bridge and is the site of the Andover Earth Station.

The land which became known as Andover was originally purchased in 1788 by a group of proprietors mostly from Andover, Massachusetts. The original proprietors were Jonathan Abbot, Philip Abbott, Ebenezer Adams, Ingalls Bragg, Samuel Farnum, Samuel Johnson, Abiel Lovejoy, Benjamin Poor, Eben Poor, Jr., and Theodore Stevens, all of Andover, Massachusetts; John York of Bethel, Massachusetts; Joseph Frye of Fryeburg, Massachusetts; and Josiah Bean, Ezekiel Merrill, and Thomas Poor of Methuen, Massachusetts. The town was first settled in 1789 by Ezekiel Merrill and his family who were transported there from Bethel, Maine, in canoes managed by members of the local Pequawket tribe. The first saw-mill was built on the East Branch of the Ellis River by Col. Thomas Poor in 1791 and was used to provide the lumber for the still standing Merrill-Poor House.

The town was incorporated on June 23, 1804, as East Andover, and then renamed Andover in 1820 when Maine separated from Massachusetts.

Occupations for early inhabitants primarily included agriculture and lumbering. As the town developed, local factories made doors, sash, blinds, starch, cheese, boots, shoes, edge-tools, carriages, and harness. The town also had a tannery. Located on an intervale surrounded by mountains, Andover is noted for "its grand and beautiful scenery," with streams abounding in trout. After the Civil War, the town became a popular destination for sportsmen, especially fishermen attracted by the nearby Richardson Lakes. A hotel was built to accommodate the influx of tourists.

In 1960, Andover was selected to be site of the Andover Earth Station, completed in 1962. It was the location of the first live transatlantic television signal broadcast by satellite Telstar 1.

According to the United States Census Bureau, the town has a total area of 57.46 square miles (148.82 km), of which 57.42 square miles (148.72 km) is land and 0.04 square miles (0.10 km) is water. Crossed by the Appalachian Trail, Andover is drained by the Ellis River, a tributary of the Androscoggin River. The river is home to many fish and wildlife, from which avid hunters and fisherman try their luck.

The town is crossed by state routes 5 and 120. It borders the towns of Roxbury and Byron to the east, Rumford to the south, Newry to the southwest, Andover West Surplus to the west, and Andover North Surplus to the north.

This climatic region is typified by large seasonal temperature differences, with warm to hot (and often humid) summers and cold (sometimes severely cold) winters. According to the Köppen Climate Classification system, Andover has a humid continental climate, abbreviated "Dfb" on climate maps.
