John Anthony Quitman (born September 1, 1798) was a Democratic politician who represented Mississippi in the United States House of Representatives during the mid-nineteenth century. Serving as a member of the House from December 3, 1855, to March 3, 1859, he held office as a representative for Mississippi’s 5th Congressional District. His tenure in Congress placed him among the historical members of that body in the years immediately preceding the American Civil War.

Quitman served two terms in the U.S. House of Representatives, reflecting sustained support from his constituents in Mississippi. As a Democratic representative, he participated in the national legislative process during a period marked by growing sectional tensions, although specific committee assignments or legislative initiatives are not recorded in the available metadata. He left office as a former member of Congress after his service concluded in 1859.
