Malibu Creek State Park is a California state park in the Santa Monica Mountains near Malibu, in Calabasas. It opened to the public in 1976.

The majority of the park's lands were donated by Bob Hope. Other parts of the park, added later, were previously owned by Paramount Pictures and 20th Century Fox for movie ranches. Part of the former 20th Century Fox Ranch had been purchased in 1966 from Ronald Reagan. The first Reagan Ranch, known as 'Yearling Row,' was owned by the future president from 1951 to 1966. It was sold by the Reagans to pay campaign debts from the 1966 California governor's campaign. The ranch life was used to develop Reagan's 'cowboy persona' used in the gubernatorial and presidential campaigns and while in each office. Additional parcels have been connected by the Santa Monica Mountains Conservancy and Santa Monica Mountains National Recreation Area.

The park is home to several culturally significant areas, including the Sepulveda Adobe, and the ruins of Mott Adobe. To the north is the former Reyes Adobe and Rancho Las Virgenes.

The park, when a movie ranch was known as the Fox Ranch and Century Ranch during its ownership by 20th Century Fox, has been used as a location in dozens of films, starting with a number of Tarzan movies:
- Tarzan Escapes (1936)
- Tarzan's Revenge (1938)
- Tarzan Finds a Son! (1939)
- Blockade (1938)
- Full Confession (1939)

- My Friend Flicka (1943)
- Mr. Blandings Builds His Dream House (1948)
- Viva Zapata! (1952)
- Between Heaven and Hell (1956)
- The Defiant Ones (1958)
- The Second Time Around (1961)
- Posse from Hell (1961)
- The Sand Pebbles (1966)
- Planet of the Apes (1968), Battle for the Planet of the Apes (1973)

- Logan's Run (1976)
- Masters of the Universe (1987)

The park was also a key filming location for the M*A*S*H series, both for the feature film and the subsequent television series. The landscape was particularly seen in the opening credits for the show as helicopters carrying wounded approach the hospital with the recognizable Goat Buttes in the background.
