Del Mar is a beach city in San Diego County, California, United States, incorporated on July 15, 1959. Del Mar is Spanish for "of the sea" or "by the sea," which reflects its location on the coast of the Pacific Ocean. Del Mar is one of only two locations where the Torrey Pine tree naturally occurs. At the southern edge of Del Mar is the Los Peñasquitos Lagoon. To the north is the San Dieguito Lagoon and the San Dieguito River, which empties into the Pacific Ocean at Del Mar.
