Blackhawk

Black Hawk is a home rule municipality located in Gilpin County, Colorado, United States. The city population was 127 at the 2020 United States Census, making Black Hawk the least populous city in Colorado. The tiny city is a historic mining settlement founded in 1859 during the Pike's Peak Gold Rush. Black Hawk is now a part of the Denver-Aurora-Lakewood, CO Metropolitan Statistical Area and the Front Range Urban Corridor.

Black Hawk is located adjacent to Central City, another historic mining settlement in Gregory Gulch. The two cities form the federally designated Central City/Black Hawk National Historic District. The area flourished during the mining boom of the late 19th century following the construction of mills and a railroad link to Golden.
