State Route 76 (SR 76) is a state highway 52.63 miles (84.70 km) long in the U.S. state of California. It is a much used east–west route in the North County region of San Diego County that begins in Oceanside near Interstate 5 (I-5) and continues east. The highway is a major route through the region, passing through the community of Bonsall and providing access to Fallbrook. East of the junction with I-15, SR 76 goes through Pala and Pauma Valley before terminating at SR 79.

A route along the corridor has existed since the early 20th century, as has the bridge over the San Luis Rey River near Bonsall. The route was added to the state highway system in 1933, and was officially designated by the California State Legislature as SR 76 in the 1964 state highway renumbering. The section of the highway through Oceanside and Bonsall is mostly a four-lane expressway; east of I-15, the roadway is mostly a two-lane highway. Originally, the entire highway was two lanes wide; west of Bonsall, the route was widened in stages, after decades of funding shortages, planning, and litigation. The California Department of Transportation (Caltrans) maintained plans to expand the entire length of the highway west of I-15 to an expressway, and as of May 2017, construction between Bonsall and I-15 was complete.
