Black's Beach is a secluded section of beach beneath the bluffs of Torrey Pines on the Pacific Ocean in La Jolla, San Diego, California, United States. It is officially part of Torrey Pines State Beach. The northern portion of Black's Beach is owned and managed by the California Department of Parks and Recreation, while the southern portion of the beach, officially known as Torrey Pines City Beach, is jointly owned by the city of San Diego and the state park, but is managed by the city of San Diego. This distinction is important as Black's Beach is most known as a nude beach, a practice that is now prohibited in the southern portion managed by the city of San Diego.

Torrey Pines State Natural Reserve is 2,000 acres (810 ha) of coastal state park located in San Diego, California, off North Torrey Pines Road. Although it is located within San Diego city limits, it remains one of the wildest stretches of land (8 km²) on the Southern California coast. It is bordered immediately on the south by Torrey Pines Municipal Golf Course and on the north by the city of Del Mar. The reserve was designated a National Natural Landmark in 1977.
