The Pacific-Union Club is a social club located at 1000 California Street in San Francisco, California, at the top of Nob Hill. It is considered to be the most elite club of the West Coast, and one of the most elite clubs in the United States, along with the Knickerbocker Club in New York, the Metropolitan Club in Washington D.C., and the Somerset Club in Boston.
It was founded in 1889, as a merger of two earlier clubs: the Pacific Club (founded 1852) and the Union Club (founded 1854). The clubhouse was built as the home for silver magnate James Clair Flood. The former Flood Mansion is located in the Nob Hill neighborhood. It was designed by Willis Polk. It is considered the first brownstone constructed west of the Mississippi River. Along with the Fairmont Hotel across the street, it was the only structure in the area to survive the San Francisco earthquake and fire of 1906.
The club figured prominently in the history of the west coast of the United States.
