The Southern Pacific Building is one of three office buildings that make up One Market Plaza along the Embarcadero in San Francisco, California. The historic 11-story, 65-metre (213 ft) building, also known as "The Landmark", was completed in 1916 and was incorporated into a 1976 development that includes Spear Tower and Steuart Tower. The building served as the headquarters for the Southern Pacific Railroad after its move from the Flood Building after ten years from 1907. The building is now owned jointly by Morgan Stanley and Paramount Group, Inc.
