Arapahoe County

Arapahoe County Boundaries

Arapahoe County is the states’s first County and was named for the Arapaho Indians who, along with the Cheyenne Indians, occupied most of Colorado when it was only a territory. At that time, Arapahoe County was much larger and stretched to western Kansas. Denver was the original County seat and remained so until 1902, when the City of Denver became a separate County. The City of Littleton became the new County seat and remains the County seat today.

Located just south of Denver, Arapahoe County spans 806 square miles. As of the 2010 census, the population was 572,003, making it the third-most populous county in Colorado.
