Crystal Cove State Park, Protected coastal wilderness in Newport Beach and Orange County, United States.

Crystal Cove State Park covers 3,936 acres between the Pacific Coast Highway and the ocean, southeast of Newport Beach. Its 3.2 miles of coastline combine pale sandy beach, eroded tan and grey bluffs topped with low green vegetation, and inland chaparral canyons. Offshore rocks break the surf, and the park includes a 1,400-acre marine conservation area.

The area was originally inhabited by the Tongva people and later became part of Spanish rancho lands. By 1864, it fell under James Irvine's control as part of his agricultural enterprise.

The Crystal Cove Historic District holds 46 beach cottages from the 1920s and 1930s, 29 of them restored and 21 available to rent. One cottage is named Painter's Cottage after the plein air painters who depicted this coastline. The Bette Midler film Beaches used a house here.

The park offers multiple entrances including Pelican Point and Reef Point along the bluffs, each with parking nearby. Visiting early in the morning or late afternoon tends to be less crowded than midday hours.

The offshore waters form a 1,140-acre underwater park, while the wider marine conservation area covers 1,400 acres. The park's bird list runs to 180 species, among them the greater roadrunner and the turkey vulture. Ten of its roughly 26 reptiles are commonly seen, including the California legless lizard and the red diamond rattlesnake.
