State Route 180 (SR 180) is a state highway in the U.S. state of California. It runs through the heart of the San Joaquin Valley from State Route 33 in Mendota through Fresno, and then east towards the Sierra Nevada to Kings Canyon National Park.
An unbuilt segment of SR 180 is defined west to Paicines. Nearly the entire 24-mile (39 km) stretch from the Kings River crossing to Cedar Grove is eligible for the State Scenic Highway System, and nearly the entire route from Paicines to Cedar Grove is part of the California Freeway and Expressway System. Two segments travel through national parks, so are not state maintained and are thus exceptions to the above: a segment through the General Grant Grove section of Kings Canyon National Park, and the far eastern end of the road inside of Kings Canyon National Park. The freeway through Fresno has the distinction of having the most heavily traveled section of road in the San Joaquin Valley. Major plans include an extension west from Mendota to Interstate 5.
