Horace Chilton (December 29, 1853 – June 12, 1932) was a printer, lawyer, and Democratic United States Senator from Texas.

[1] At 19 he was admitted to the bar and served as assistant attorney general of Texas between 1881 and 1883 and as a delegate to the Democratic national conventions of 1888 and 1896.

Appointed to the Senate upon John H. Reagan's resignation in 1891, Chilton was the first native Texan to serve in the United States Congress.

Chilton decided not to run for reelection in 1901, returning to practice law in Tyler and later Beaumont, Texas, where he worked with Spindletop oilfield operations.
