Andrew Molera State Park is a 4,800 acres (1,900 ha), relatively undeveloped state park on the Big Sur coast of California, United States, preserving land as requested by former owner Frances Molera. Situated at the mouth of the Big Sur River, the property was part of the Rancho El Sur land grant, and later owned by Californio pioneer John Bautista Rogers Cooper and his descendants. Cooper's grandchildren Andrew and Frances Molera inherited the property from their mother in 1918. Andrew popularized the artichoke in California in 1922, and died in 1931. In 1965, Frances sold the property to The Nature Conservancy, stipulating that the park to be created should be named for her brother.

Rancho El Sur was a 8,949.06-acre (36.22 km2) Mexican land grant in present-day Monterey County, California, on the Big Sur coast given in 1834 by Governor José Figueroa to Juan Bautista Alvarado. The grant extended from the mouth of Little Sur River inland about 2.5 miles (4.0 km) over the coastal mountains and south along the coast past the mouth of the Big Sur River to Cooper's Point. In about 1892, the rancho land plus an additional 3,000 acres (1,200 ha) of resale homestead land was divided into two major parcels. The southern 4,800 acres (1,900 ha) became the Molera Ranch, later the foundation of Andrew Molera State Park. The northern 7,100 acres (2,900 ha) form the present-day El Sur Ranch.
