Zane Grey Estate, Mediterranean Revival residence in Altadena, United States.

The Zane Grey Estate is a Mediterranean Revival home in Altadena, California, built with reinforced concrete, stucco walls, and tile roofs. A rooftop addition sits above the main floors and contains a studio and library, while the lower levels are divided into separate residential units.

The house was built in 1907 for Arthur Woodward and bought in 1920 by the writer Zane Grey, who used it as a home and working retreat. In 2002 it was added to the National Register of Historic Places.

The house is named for the Western novelist Zane Grey, who bought it in 1920 with his wife after honeymooning in Altadena. The Greys added a rooftop studio and library, where he wrote; the grounds were later subdivided and sold off by their son Romer in 1970.

The estate sits in a residential area of Altadena and is easy to spot from the street thanks to its tile roofs and stucco exterior. Some parts of the building are available for short-term rental, which gives visitors a way to see the interior more closely.

Edith Norton Woodward, wife of builder Arthur Herbert Woodward, survived the 1903 Iroquois Theater Fire in Chicago, and it was at her insistence that the 1907 house was built entirely of reinforced concrete, making it Altadena's first fireproof home. In January 2025 the Eaton Fire destroyed the house, leaving only some of those concrete walls standing.
