The Berkeley Hills are a range of the Pacific Coast Ranges which overlook the northeast side of the valley in which San Francisco Bay is situated. They were originally called the Contra Costa Hills, but with the establishment of Berkeley and the University of California, the current usage was applied.

In recent years, that part of the same range of hills which continues into Oakland, are often referred to as the "Oakland Hills", but properly, they remain part of the Berkeley Hills.

Tectonically, the Berkeley Hills are bounded by the Hayward Fault along their western base, and the Wildcat Fault on their eastern side.

The highest peaks are Vollmer Peak elevation 1,905 ft, Grizzly Peak (elevation 1,754 feet/535 m) and Round Top (elevation 1,761 feet/537m).
