Andrew Jackson Bryant, known as A.J. Bryant, (1831–1888) was the seventeenth mayor of San Francisco, California, serving from December 1875 to December 1879 during a lengthy economic depression that struck San Francisco and the rest of the country. Bryant was a strong advocate for an eight-hour work day as well as legislation to halt the immigration of Chinese laborers into the state. A prominent insurance man and a sportsman, he drowned in the San Francisco Bay after falling from a ferryboat.
