Rose McConnell Long was an American politician who served as a U.S. senator from Louisiana, succeeding her late husband Huey Long. She was the third woman to serve as a U.S. senator, and the first from Louisiana.

Huey Pierce Long Jr., nicknamed "The Kingfish", was an American politician who served as the 40th governor of Louisiana from 1928 to 1932 and as a United States senator from 1932 until his assassination in 1935. He was a left-wing populist member of the Democratic Party and rose to national prominence during the Great Depression for his vocal criticism of President Franklin D. Roosevelt and his New Deal, which Long deemed insufficiently radical. As the political leader of Louisiana, he commanded wide networks of supporters and often took forceful action. A controversial figure, Long is celebrated as a populist champion of the poor or, conversely, denounced as a fascistic demagogue.
