Union Square is a central public plaza and commercial district in downtown San Francisco, known as a focal point for shopping, hotels and cultural activity since the 19th century.

The site was established during San Francisco’s rapid 19th-century growth and took the name Union Square in the 1860s following pro-Union gatherings during the American Civil War. It evolved into a retail and hotel district through the 20th century and remains a major commercial center.

Union Square sits in the heart of San Francisco’s downtown, a short walk north of Market Street and adjacent to major streets including Powell and Geary; its central position places it within walking distance of many downtown transit connections.

• Central location: Located two blocks north of Market Street in downtown San Francisco and surrounded by major department stores, hotels and theaters.
• Events and use: Hosts a seasonal ice rink and public events; the plaza sees heavy foot traffic year-round and is a major shopping district focal point.

What to See#

• Union Square Park: A roughly triangular landscaped public park covering about 2.6 acres at the heart of the plaza, with art, seating and seasonal plantings.
• Powell Street cable car turnaround: The Powell Street cable car turnaround and boarding area sit at the southwest edge of the square and provide a major visitor transport link and photo opportunity.

Union Square is served directly by Powell Street BART and Muni; both the Powell St. BART station and several Muni bus and streetcar lines stop within a block of the square. The Powell-Hyde and Powell-Mason cable car lines terminate nearby at Powell and Market streets.

• Use Powell Street BART for the quickest access; the Powell Station is one block from the square.
• Avoid weekend afternoons if the goal is to shop without crowds - midweek mornings are far quieter.
• Don't miss the Dewey Monument and the pedestrian arcade that runs up to Geary Street for window shopping and people-watching.
