Lancaster is an unincorporated community in Smith County, Tennessee, United States, located 5.3miles southeast of Gordonsville. Lancaster had a post office with ZIP code 38569, which closed on March 4, 2011, due to the United States Postal Service closing smaller post offices around the country.[2] [3] [4]
As of 2010, the population of Lancaster's zip code tabulation area was 363. The community is situated along State Highway 141 between Gordonsville and Center Hill Lake, and is drained by Smith Fork, a tributary of the Caney Fork. Lancaster is named for John Lancaster, Jr., an early settler who arrived in the area in the late 18th century (his family still owns a farm in the area, which has been designated a Tennessee Century Farm).[5]
