The Town of Fairfield is located in southern Somerset County in the heart of Maine's Kennebec Valley, and straddling the Waterville and Skowhegan "micropolitan" areas. The town is bound on the East by the historic Kennebec River and to the west by the Belgrade Lakes region.

Fairfield is known as an important crossroads and is the point of intersection of two of the largest transportation corridors in the state, U.S. Route 201 and Interstate 95. Fairfield is home to many thriving businesses, and with 55 square miles also contains large areas of developable land. The town has a substantial urban residential and historic downtown district and several quaint unincorporated villages that contribute to its charm and character.

With a local community college and regional high school, an easy commute to anywhere in central Maine, and unrivaled access to outdoor sports and recreation, many families find Fairfield the perfect place to reside.
