Barzillai Jefferson Chambers (December 5, 1817 – September 16, 1895) was an American surveyor, lawyer, and politician of the Gilded Age. Born in Kentucky, he moved to Texas to join its war for independence against Mexico. Chambers stayed in Texas after its independence and annexation by the United States, earning a living as a surveyor and farmer in Johnson County. In the American Civil War, he served briefly in the Confederate army, then returned to his farming and business interests, becoming part-owner of a bank in his hometown of Cleburne. In the 1870s, Chambers became concerned with farming and monetary issues in politics, eventually joining the nascent Greenback Party in 1877. He ran unsuccessfully for Vice President on the Greenback ticket with presidential nominee James B. Weaver of Iowa in 1880. The Greenback nominees finished in a distant third place, receiving only 3.3% of the popular vote and no electoral votes. After the election, Chambers remained active in Greenback politics in Texas until the party's demise in the late 1880s. He died at his home in Cleburne in 1895.
