The city is located within what was once the James Ranch, owned by Jefferson G. James (1829–1910). In 1912, the 76,000 acre ranch was bought by Benjamin F. Graham (1868–1935), who announced his intent to sell it in 60-to-80 acre tracts.[10] The nucleus of the land development project would be a new city near Tranquillity, named "Graham", for which construction began immediately, including an announced plan for a railroad spur line leading to it to be laid "within two weeks".[11]

On April 16, 1913, a post office named "Grahamton" opened there, but two days later its name was changed to "San Joaquin".[12][8] The city and associated development continued to be promoted as "Graham" until about August of that year, after which it was referred to as "San Joaquin".

San Joaquin was incorporated in 1920, becoming the tenth incorporated municipality in the county.[13][8]

In a county dominated by the agriculture industry, San Joaquin residents mostly work on farms. The city suffers from poverty, and poor educational standards and achievements.
