The 1 California is a trolleybus line operated by the San Francisco Municipal Railway (Muni). It provides service between the Richmond District and Financial District along California Street.

From the outbound terminal at Geary Boulevard and 33rd Avenue, buses loop around the block to run north on 32nd Avenue. The route then operates on California Street between 32nd and Steiner. The line continues eastward a block further north on Sacramento Street. Between Gough and the terminal at Clay and Drumm, the line runs with the direction of the one-way streets Sacramento (westbound) and Clay (eastbound).

The outbound segment of the express lines match that of the local service. The 1AX California 'A' Express running nonstop between 8th Avenue and Montgomery Street and the 1BX California 'B' Express terminates at 6th Avenue and runs express after Fillmore Street. The eastern end of the line terminates adjacent to Embarcadero station and runs via an overlapping loop on one-way streets.

During the COVID-19 pandemic, 1AX and 1BX service was suspended. Express service on California Street resumed with the 1X line on February 21, 2023. The 1X terminates at Geary and 33rd Avenue and runs express east of Arguello Boulevard. The line also serves an additional terminus near the Embarcadero Center in evening peak hours.

Market Street Railway operated the 1 California streetcar between the Ferry Building and the Sunset on a route primarily via Sutter Street, California Street, Clement Street, and Geary Street.^[2]

The C Geary–California streetcar route was the third Muni line to open in 1913.^[3] It ran from ran from the Ferry Building along Market Street, Geary, 2nd Avenue, Cornwall, and California to 33rd Avenue.^[4] The route was cut short in 1950 to California and 2nd Avenue with the opening of the 1 California bus line, and was removed along with the B Geary on December 29, 1956.^[5][6]

The 1 California and 55 Sacramento were combined to form the current 1 California line on January 27, 1982.^[7][8]

Additional short turn service between Presidio Avenue and Drumm Street was added on June 10, 2023, and morning 1X service was increased from three to five trips.^[9]

A fictionalized version of the 1 California is featured in a chase scene in the 2021 Marvel film Shang-Chi and the Legend of the Ten Rings. In Shang-Chi, the titular protagonist and his best friend Katy are confronted onboard a 1 California bus by Razor Fist and other members of the Ten Rings, who attempt to steal a pendant from Shang-Chi. In their fight, Razor Fist slices through the articulation joint of the articulated bus, disabling the brakes and sending the bus downhill through Nob Hill. As Shang-Chi and the members of the Ten Rings fight inside the bus, the bus begins to split apart while Katy attempts to regain control. Shang-Chi pulls the stop request cord, signaling Katy to split the bus and leave Razor Fist behind in the back half. The front of the bus crashes into a row of parked cars outside Ghirardelli Square.^[10][11]

The 1 California bus in Shang-Chi featured the logos of the fictional "SFT," as Muni did not want their brand associated with the destruction of the action sequence. Much of the scene was filmed in a studio in Australia, with parts of the sequence filming on location in the Richmond District in October 2020. The route of the fictional 1 Califonia was generally accurate, with modifications made to feature the Stockton Street Tunnel and Ghirardelli Square, neither of which are destinations on the real 1 California.^[12] The chase scene on the 1 California was well-received, with San Francisco Chronicle critic Peter Hartlaub describing it as the second-best San Francisco car chase scene of all time, second only to Bullitt (1968).^[10]
