The Bradshaw Mountains (Yavapai: Wi:kañacha, "rough, black range of rocks") are a mountain range in central Arizona, United States, named for brothers Isaac and William D. Bradshaw after their deaths, having been formerly known in English as the Silver Mountain Range.

Located approximately 5 miles south of Prescott, Arizona, between the Agua Fria River on the east, and the Hassayampa River on the west, the range is 40 miles long, and almost 25 miles wide.

History
The first known settlements in the Bradshaws were a group of Yavapai people, called the Kwevkapaya who built forts and mined copper from around AD 1100 to 1600. The Walker party found gold, and within a few years, the Bradshaws were filling up with settlers mining for gold, silver, and copper. In the early part of the 20th century, most of the towns that had sprung up were little more than ghost towns.
