Allen Joseph Ellender (September 24, 1890 – July 27, 1972) was an American politician and lawyer who was a U.S. senator from Louisiana from 1937 until his death in 1972. He was a Democrat who was originally allied with Huey Long. As Senator he had a generally conservative record, voting 77% of the time with the Conservative Coalition on domestic issues. A staunch segregationist, he signed the Southern Manifesto in 1956, voted against the Voting Rights Act of 1965, and opposed anti-lynching legislation in 1938. Unlike many Democrats he was not a "hawk" in foreign policy and opposed the Vietnam War.

Ellender served as President Pro Tempore, and the chair of the Senate Appropriations Committee. He also served as the chair of the Senate Agriculture Committee for over 18 years.
