Dearborn is an extinct town, now split among the towns of Fairfield, Smithfield, and Mercer in Somerset County, and the towns of Rome, Belgrade, and Oakland in Kennebec County. The town of Dearborn was formed from the West Pond Plantation in 1812, but that town status was surrendered in 1841. In 1843 Dearborn was annexed to Waterville, Maine.
