Rockford is a city in Blount County, Tennessee, United States. Its population was 798 at the 2000 census and 856 at the 2010 census. It is included in the Knoxville, Tennessee Metropolitan Statistical Area.
Rockford is named for a river ford used by early 19th-century settlers and merchants travelling between Knoxville and Maryville. As its name implies, the ford was unusually rocky, and thus preferred by travellers, as large amounts of silt and sand made much of the Little River difficult to cross. The community was called "Rocky Ford" by the early 1800s.
Rockford incorporated as a city in the early 1970s to avoid being annexed by Alcoa or Maryville, both of which were growing rapidly.
