The Henderson area was the first permanent settlement in the county area. It was on a large island in the South Platte River. Many of these settlers first arrived to strike it rich in the gold rush, but found they did better by providing food and supplies to the other miners and to residents of the city of Denver. The agricultural roots of the county are still maintained today. The first depot in the county was named Hughes, but the name was later changed to Brighton when the town was platted. Brighton was the first incorporated town in the county in 1887. Adams County was created in 1902 from a part of the very large Arapahoe County. It was named for Alva Adams, a former governor who actually held the office at the time. Brighton was chosen as the county seat on 8 November 1904. A courthouse was built in 1906. The building is still used for other purposes today.

In 1903, part of the eastern county was moved to the new counties of Washington and Yuma. In 1989, 53 square miles was transferred to the City and County of Denver for the new Denver International Airport. A small corner of the county went to the City and County of Broomfield on 15 November 2001.
