Sepulveda Pass, Mountain pass in Santa Monica Mountains, California.

Sepulveda Pass is a mountain crossing through the Santa Monica Mountains that connects the San Fernando Valley to Los Angeles's Westside at approximately 1,130 feet elevation. Interstate 405 serves as the primary route through this passage, handling traffic flow between both regions.

Sepulveda Pass is named after the Sepúlveda family, a prominent Californio family that owned the land where the pass lies. Bel Air Presbyterian Church, founded in 1956, opened its church on Mulholland Drive in 1960. From 1965, when The Westland School arrived, schools and cultural institutions gathered along the crest, forming an institutional corridor exempted from the Mulholland Scenic Parkway Specific Plan's ban on such development.

Mulholland Drive above the pass holds an institutional corridor exempted from the scenic parkway plan's ban on such building: Bel Air Presbyterian Church opened there in 1960, The Westland School arrived in 1965, and the Skirball Cultural Center, Stephen S. Wise Temple and American Jewish University followed. The Getty Center campus lies to the south.

Interstate 405 is the main highway traversing the pass with multiple lanes in each direction, including carpool lanes. Visitors should expect heavy traffic, especially during rush hours, and may want to consider using Mulholland Drive as an alternative route.

Sepulveda Boulevard runs west of I-405 until the middle of the pass, where it crosses under the freeway and continues east of it. Northbound I-405 has five lanes plus a carpool lane, and a climbing lane is added on the ascent.
