Marmaduke Williams (6 April 1774 - 29 October 1850) was a Democratic-Republican U.S. Congressman from North Carolina from 1803 to 1809.
Born in Caswell County, North Carolina, Williams studied law and was admitted to the North Carolina bar. He was elected to the North Carolina State Senate, serving 1802, and then was elected that same year to the 8th United States Congress. Williams was re-elected twice, serving in the 9th and 10th Congresses (March 4, 1803 - March 3, 1809). He declined to run for a fourth term and moved to the Mississippi Territory in 1810, then to Huntsville, Alabama.
Williams was a delegate to the Alabama Constitutional Convention of 1819 and ran unsuccessfully that year for the post of Governor of Alabama. He served in the Alabama State House of Representatives from 1821 to 1839, and was a judge of the Tuscaloosa County court from 1832 to 1842. He died in Tuscaloosa in 1850 and is buried in Greenwood Cemetery.
