The Superior Court of California of the County of San Francisco is the state superior court with jurisdiction over the City and County of San Francisco.

Courthouse functions were incorporated into San Francisco City Hall prior to 1997. The village of Yerba Buena, seized by Commodore John D. Sloat in July 1846, was renamed to San Francisco in January 1847.^{[4]: 104, 110} Initially, the Custom House on Brenham Place and Washington Street was used for municipal offices.^[4]: 147

With the influx of immigrants seeking gold during the California Gold Rush in 1849, the population swelled and a nativist gang calling themselves The Hounds began harassing Spanish-American immigrants.^[4]: 148 The first court system was organized after a public meeting on July 16, 1849, demanding the Hounds be brought to justice; the leaders were put on trial and sentenced to ten years imprisonment and the leaderless organization dissolved shortly thereafter.^[4]: 149 Subsequently, planning began for the first California Constitutional Convention and a local election was held on August 1, 1849, naming ten delegates; these men were advised by John W. Geary, the recently-elected First Alcalde (equivalent to the mayor), that "in the absence of any state legislative authority, they were supreme in the district" as the ayuntamiento (town council, equivalent to the modern San Francisco Board of Supervisors).^[4]: 143

After the first state constitution was adopted, a city charter was passed in the state legislature and a subsequent election in May 1850 saw Geary elected as the first mayor.^[4]: 155 The city offices had outgrown the Custom House and the Graham House, built initially as a four-storey hotel on the northwest corner of Kearny and Pacific, was purchased for US$150,000 (equivalent to $5,494,000 in 2023) to serve as the new City Hall.^[4]: 156 Members of a group that previously had held a vigilante justice trial in February 1851 continued the legacy of the Hounds, later forming the San Francisco Committee of Vigilance in June 1851.^{[4]: 172–173} The Graham House was destroyed during the fifth "great fire" of June 22, 1851, and the former Jenny Lind Theater was purchased in 1852 for US$200,000 (equivalent to $7,325,000 in 2023) to serve as a replacement City Hall and Courthouse.^{[4]: 170, 184}

Gold mine production peaked during the winter of 1852–53 and many miners left the city;^{[4]: 216–217} by 1855, the population boom and bust had produced what historian John Hittell called "a greater depth of [political] corruption in San Francisco than in any other part of the United States. The people were new-comers, not long acquainted with their leading men, and their officials were selected at random."^[4]: 241 Notable failures of justice, including the fraud of Henry Meiggs and the murder of James King of William, led to the revival of the Committee of Vigilance in May 1856,^{[4]: 243–246} which subsequently was dissolved that August.^[4]: 259

In 1870, Yerba Buena Square, previously used as the city cemetery in the 1850s,^[5]: 516 was graded to prepare for the construction of the first purpose-built City Hall.^[4]: 382 Plans from Augustus Laver were selected and construction began in 1871 but the building was not completed until a quarter-century later, in 1895.^{[5]: 712–713} As historian John P. Young wrote in 1912, "The cost as originally estimated was quite modest, but there were plenty of critics who declared that it would be largely exceeded. The most pessimistic, however, did not even remotely approach the truth in making their guesses."^[6]: 406 It was destroyed during the April 1906 San Francisco earthquake and subsequent fire.

In 1976 the Court helped to create the San Francisco Pretrial Diversion Project,^[7] a nonprofit organization that helps to provide alternative punishments for misdemeanors and parking violations, in an attempt to divert petty offenders from overcrowded courtrooms.^[8]
