Whittier Mansion, Historic mansion in Pacific Heights, San Francisco, United States.

The Whittier Mansion is a four-story, 30-room residence at 2090 Jackson Street, built with steel-reinforced brick walls faced in Arizona red sandstone. Each floor has about 3,500 square feet of living space; the second floor holds six bedrooms, three with private marble bathrooms.

William Franklin Whittier built the mansion in 1894–1896, paying for it with instalments from the 1893 sale of his paint firm to the Fuller family. After his death in 1917 his daughter Mattie Weir rented it out. In April 1941 the title passed through intermediaries to the German Reich, which paid $44,000 in cash for a consulate that closed on 15 July 1941.

The mansion displays Richardsonian Romanesque and Renaissance elements, visible through carved mahogany panels and detailed metalwork throughout its rooms. The interior craftsmanship reflects the building traditions valued by wealthy families in turn-of-the-century San Francisco.

The mansion is a private building at 2090 Jackson Street, between Laguna and Buchanan in Pacific Heights, and is not open for regular public tours. Visitors can view the Arizona red sandstone facade from the sidewalk; interior access is only possible during occasional private events.

The Nazi consulate occupied the mansion for less than three months, from April 1941 until German diplomats were expelled on July 15, 1941. Neighbours hired attorney Marvin Lewis to appeal the move before the San Francisco Planning Commission, and agent Charles M. Dufficy sued for his commission after being sidelined.
