Louis Trezevant Wigfall (April 21, 1816 – February 18, 1874) was an American politician who served as a Confederate States Senator from Texas from 1862 to 1865.
He was among a group of leading secessionists known as Fire-Eaters, advocating the preservation and expansion of an aristocratic agricultural society based on slave labor.
He briefly served as a Confederate Brigadier General of the Texas Brigade at the outset of the American Civil War before taking his seat in the Confederate Senate.
Wigfall's reputation for oratory and hard-drinking, along with a combative nature and high-minded sense of personal honor, made him one of the more imposing political figures of his time.
