Jesse Fuller (March 12, 1896 – January 29, 1976) was an American one-man band musician, best known for his song “San Francisco Bay Blues“.

In the 1920s he lived in southern California, where he operated a hot-dog stand and was befriended by Douglas Fairbanks. He worked briefly as a film extra in The Thief of Bagdad (1924) and East of Suez. In 1929 he settled in Oakland, across the bay from San Francisco, where he worked for the Southern Pacific Railroad for many years as a fireman, spike driver, and maintenance-of-way worker. He married, and he and his wife, Gertrude, had a family. During World War II, he worked as a shipyard welder, but when the war ended he found it increasingly difficult to secure employment. Around the early 1950s, Fuller began to consider the possibility of making a living as a musician.

Up to this point, Fuller had never worked as a full-time professional musician, but he was an accomplished guitarist and he had carried his guitar with him and busked for money by passing the hat. He had a good memory for songs and had a large repertoire of crowd-pleasers in diverse styles, including country blues, work songs, ragtime and jazz standards, ballads, spirituals, and instrumentals. For a while, he operated a shoe-shine stand, where he sang and danced to entertain passersby. He began to compose songs, many of them based on his experiences on the railroads, and also reworked older pieces, playing them in his syncopated style. When he set out to make a career as a musician, he had difficulty finding reliable musicians to work with: thus his one-man band act was born, and he started calling himself “The Lone Cat.”
