Farmington is a town in Hartford County in the Farmington Valley area of central Connecticut in the United States. The population was 25,340 at the 2010 census. It sits 10 miles west of Hartford at the hub of major I-84 interchanges, 20 miles south of Bradley International Airport and two hours by car from New York City and Boston. It is home to the world headquarters of several large corporations including Otis Elevator Company and Carvel. The northwestern section of Farmington has a Unionville suburban neighborhood.
Farmington was originally inhabited by the Tunxis Indian tribe. In 1640, a community of English immigrants was established by residents of Hartford, making Farmington the oldest inland settlement west of the Connecticut River and the twelfth oldest community in the state. Settlers found the area ideal because of its rich soil, location along the floodplain of the Farmington River, and valley geography.
The town and river were given their present names in 1645, which is considered the incorporation year of the town. The town's boundaries were later enlarged several times, making it the largest in the Connecticut Colony.
