Governor's Mansion State Historic Park, Victorian mansion in downtown Sacramento, United States.

Governor's Mansion State Historic Park preserves a three-story residence with thirty rooms built in the Second Empire style mixed with Italianate details. The facade shows characteristic mansard roofs and decorative elements, while inside the layout spreads living quarters, reception halls, and private chambers across multiple floors.

Built in 1877 for hardware merchant Albert Gallatin, the thirty-room mansion was sold to businessman Joseph Steffens in 1887 and bought by the State of California in 1903. Governors occupied it until 1967, when ownership passed to California State Parks; it reopened in 1970 as a historic house museum. Jerry Brown moved back in after 2015 renovations, and Gavin Newsom lived there briefly in 2019.

The name reflects its function as the official home where California's governors lived and worked for more than six decades. Visitors today see furniture and personal items left behind by the families who made decisions affecting the entire state from these rooms.

The carriage house on the property serves as the entrance with a gift shop and orientation point for visitors. The park sits in the downtown area and is easy to reach on foot from nearby hotels and other sites.

Fourteen governors have used the mansion as the executive residence, from its purchase by the state in 1903 to Jerry Brown's return in 2015. Furnishings from several administrations remain, among them George C. Pardee's 1902 Steinway piano, Hiram Johnson's velvet chairs and sofas, and Persian rugs bought by Earl Warren's wife.
