Harold Lloyd Estate, Mediterranean Revival mansion in Beverly Hills, United States.

The Harold Lloyd Estate is a residential complex with 44 rooms in Beverly Hills, designed in Spanish Colonial, Renaissance, and Mediterranean Revival styles. The buildings display white stucco facades, red tile roofs, and sprawling gardens across 5 acres (2 hectares).

Harold Lloyd bought the 15-acre Benedict Canyon site from the Benedict family in May 1923 for $100,000. Construction of the 44-room mansion, designed by Sumner Spaulding, began in July 1927 and was completed in 1928. After Lloyd's death in 1971, the lower acreage along Benedict Canyon was subdivided into about 15 home lots, leaving the hilltop mansion roughly 5 acres. The estate was listed on the National Register of Historic Places in 1984.

Lloyd named the estate Greenacres, and Sundays were its "at home" day: 30 or 40 friends played golf, tennis or handball, swam, strolled the gardens, took a buffet in the formal dining room, and watched a movie before Lloyd waved them goodnight. In 1937 his wife hosted a bridal shower there for Jeanette MacDonald, attended by Ginger Rogers, Mary Pickford and Dolores del Río.

The estate stands at the mouth of Benedict Canyon in Beverly Hills, on a hilltop above the canyon road; the lower canyon acreage was divided into about 15 house lots, so the mansion is not visible from the street. It is a private single-family home with no public tours or visitor access.

The property originally featured a canoe run measuring 900 feet (274 meters) in length and a nine-hole golf course. The swimming pool was the largest private pool in Southern California when completed.
