Apple Valley is a city in northwestern Dakota County, Minnesota, and a suburb of the Twin Cities. The population was 56,374 at the 2020 census, making it the 17th most populous city in Minnesota. The area that became Apple Valley was first established in 1859 as Lebanon Township, and remained a farming community for nearly a century. In the mid-1950s, residential developments started replacing farmland. Orrin Thompson, a real estate developer, was responsible for the city's early development. He contracted a company to determine where the next growth in the Twin Cities would be. It was 0.5 miles from County Road 42 and Cedar Avenue. Thompson bought the first houses and streets from the Brobacks, who built the city's first four houses. The firm that selected this area was in Apple Valley, California, so Thompson took that name for the development. An alternate explanation for the name change exists, however. According to local developer Henry Broback, Lebanon Township was renamed Apple Valley because "...when you drive east on 42 and turn to enter Lebanon, it reminded them of Apple Valley, California, which was a nice community."
