 The city, formerly Firebaugh's Ferry, is named for Andrew D. Firebaugh (also spelled Fierbaugh, born in Virginia in 1823), an area entrepreneur. During the Gold Rush, Firebaugh's most famous local enterprise was a ferry boat which shuttled people across the San Joaquin River. In 1857, he built a toll road for wagons, replacing an earlier horse trail that ran parallel to present-day State Route 152 from what became Bell Station over Pacheco Pass to the Rancho San Luis Gonzaga.
 Firebaugh was a station on the Butterfield Overland Stage. The Firebaugh's Ferry post office operated from 1860 to 1862. The Firebaugh post office opened in 1865.
 In the 1880s, the area of Firebaugh was once part of the massive holdings of the Miller and Lux Company, which had a large cattle operation covering what today is Dos Palos to Mendota.
