Laguna Summit is a pass through the Cuyamaca Mountains of southeastern San Diego County, California, traversed by Interstate 8 at an altitude of 4,055 feet (1,236 m). Together with Crestwood Summit and the Tecate Divide it forms the westernmost of the three high points of Interstate 8 as it passes through the Cuyamaca Mountains. It is located east of Pine Valley, just to the east of the intersection with the Sunrise Highway, which heads north towards the Laguna Mountains. The pass is also traversed by Old Highway 80 (now County Route S1, continuing to the east from the Sunrise Highway as a frontage road of Interstate 8).
