Paul David Wellstone (July 21, 1944 – October 25, 2002) was an American academic, author, and politician who represented Minnesota in the United States Senate from 1991 until he was killed in a plane crash near Eveleth, Minnesota, in 2002. A member of the Democratic Party (DFL), Wellstone was a leader of the populist and progressive wings of the party.

Born in Washington, D.C., Wellstone grew up in Northern Virginia. He went on to graduate from the University of North Carolina at Chapel Hill with a Bachelor's of Arts and a doctorate in political science. In 1969, Wellstone was hired as a professor at Carleton College in Northfield, Minnesota, where he taught until his election to the Senate in 1990. In addition, he also worked as a local activist and community organizer in rural Rice County. In 1982, he made his first bid for political office in that year's Minnesota State Auditor race. His campaign was unsuccessful, losing to Republican incumbent Arne Carlson.
