Eustis was first called Township No. 1 of Range 4, West of Bingham's Kennebec Purchase. The original settler was Caleb Stevens from New Hampshire, who brought his wife and nine children. About 1831, the northern half of the township was purchased from the state of Maine by two men, one of whom was Charles L. Eustis of Lewiston. That same year he built a sawmill and gristmill. In 1840, the township was organized as Hanover Plantation, which about 1850 became part of the larger Jackson Plantation. On March 30, 1857, however, the township was set off and organized as Eustis Plantation, named after its early proprietor. Then on February 18, 1871, with a population of 342, it was officially incorporated as a town. 
According to the United States Census Bureau, the town has a total area of 41.48 square miles (107.43 km2), of which, 39.13 square miles (101.35 km2) of it is land and 2.35 square miles (6.09 km2) is water.  Eustis is drained by the Dead River.
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, Eustis has a humid continental climate, abbreviated "Dfb" on climate maps.
