State Route 79 (SR 79) is a state highway in the U.S. state of California. The route begins at Interstate 8 (I-8) in San Diego County, continuing north through the town of Cuyamaca into Julian. After passing through Warner Springs, the route crosses into Riverside County, providing access to the cities of Temecula and Murrieta. SR 79 ends at I-10 in Beaumont.

SR 79 begins at exit 40 of I-8, about 40 miles (64 km) from its western terminus and approximately 35 miles (56 km) east of San Diego. The road runs along Old Highway 80 in the town of Descanso, until splitting to the north at a T intersection. The route then traverses Cuyamaca and Cuyamaca Rancho State Park on its way north. This portion of the route is very serpentine, with hairpin turns, as it follows the contours of the land by moving laterally, rather than up-and-down or via cuts.
