State Route 91 (SR 91) is a major east–west state highway in the U.S. state of California that serves several regions of the Greater Los Angeles urban area. A freeway throughout its entire length, it officially runs from Vermont Avenue^[3] in Gardena, just west of the junction with the Harbor Freeway (Interstate 110, I-110), east to Riverside at the junction with the Pomona (SR 60 west of SR 91) and Moreno Valley (SR 60 and I-215 east of SR 91) freeways.

Though signs along the portion from Vermont Avenue west to Pacific Coast Highway (SR 1) in Hermosa Beach along Artesia Boulevard are still signed as SR 91, the California Department of Transportation (Caltrans) no longer controls this portion of the highway, as this segment was relinquished to local jurisdictions in 2003.^[3]

SR 91 inherited its route number from the mostly decommissioned U.S. Route 91 (US 91), which passed through the Inland Empire in a northeasterly direction on its way to Las Vegas, Salt Lake City, and points beyond. Those segments of US 91 are now parallel to, or have been replaced altogether by, I-15.
