State Route 371 (SR 371) is a state highway in Riverside County in the U.S. state of California, serving as a short connector of from SR 79 near Aguanga to SR 74 near Anza. It is a heavily-used shortcut from southwestern Riverside County to the Coachella Valley in central Riverside County via SR 74. The current route was part of SR 71 until 1973, when SR 79 and SR 71 were co-signed from Aguanga to Temecula. In 1974, the portion of SR 71 from Temecula to Corona along I-15's current alignment was deleted, and the orphaned route from Aguanga to Anza was re-signed as SR 371.
