Douglas County is a county located in the U.S. state of Colorado. As of the 2020 census, the population was 357,978. The county seat is Castle Rock.
Douglas County is part of the Denver-Aurora-Lakewood, Colorado, metropolitan statistical area. It is located midway between Colorado's two largest cities, Denver and Colorado Springs, and contains a portion of Aurora, the state's third-largest city. Douglas County has the highest median household income of any Colorado county or statistical equivalent. It is ranked seventh nationally in that category.
Douglas County is lightly wooded, mostly with ponderosa pine, with broken terrain characterized by mesas, foothills and small streams. Cherry Creek and Plum Creek rise in Douglas County and flow north toward Denver and into the South Platte River. Both were subject to flash flooding in the past, Plum Creek being partially responsible for the Denver flood of 1965. Cherry Creek is now dammed.
Most residents commute to workplaces elsewhere in the metropolitan area outside of the county. Suburban development is displacing the ranching economy of the county.
Douglas County was one of the original 17 counties created in the Colorado Territory by the Colorado Territorial Legislature on November 1, 1861. The county was named in honor of U.S. Senator Stephen A. Douglas of Illinois, who died five months before the county was created. The county seat was originally Franktown, but was moved to California Ranch in 1863, and then to Castle Rock in 1874. Although the county's boundaries originally extended eastward to the Kansas state border, in 1874 most of the eastern portion of the county became part of Elbert County.
According to the U.S. Census Bureau, the county has a total area of 844 square miles (2,190 km2), of which 841 square miles (2,180 km2) is land and 2.6 square miles (6.7 km2) (0.3%) is water.
