Barrington Hills is a village located about 40 miles (64 km) northwest of Chicago in the U.S. state of Illinois. It straddles approximately 29 square miles (75 km2) over four counties, Cook, Kane, Lake, and McHenry. The population was 4,209 at the 2010 census. The Village of Barrington Hills was incorporated in 1957.
The suburban village is included in the greater Barrington area. Many very affluent residents live on large estates and commute to downtown Chicago. A minimum 5-acre (2.0 ha) zoning restriction has been in effect on new construction since 1963, but the existence of equestrian farms antedates the village by decades. Farming and horse raising are allowed. Barrington Hills includes farms and estates such as Hill 'N Dale Farms, owned by Richard L. Duchossois, former owner of the Arlington Park racetrack, and the Bank Note Farm. The identification of the area with horses carries over to the names Broncos and Colts for school teams.
Barrington Center Church was built in 1853 by the Barrington Methodist Episcopal Society.
