The Berkeley Hills Tunnel is a tunnel which carries Bay Area Rapid Transit (BART) Yellow Line through the Berkeley Hills between Rockridge station and Orinda station.

The Berkeley Hills are a range of the Pacific Coast Ranges that overlook the northeast side of the valley that encompasses San Francisco Bay. They were previously called the "Contra Costa Range/Hills", but with the establishment of Berkeley and the University of California, the current usage was applied by geographers and gazetteers.
