Joseph Robert Kerrey (born August 27, 1943) is an American politician who served as the 35th governor of Nebraska from 1983 to 1987 and as a United States Senator from Nebraska from 1989 to 2001. Before entering politics, he served in the Vietnam War, as a United States Navy SEAL officer and was awarded the Medal of Honor for bravery in combat. During the action for which he was awarded the Medal of Honor, he was severely wounded, precluding further naval service. He later faced controversy for being the commanding officer during the Thanh Phong raid, where numerous civilians were killed.

Kerrey was a candidate for the Democratic presidential nomination in 1992. He retired from the Senate in 2000 and was replaced by former governor and fellow Democrat Ben Nelson. From 2001 to 2010, he served as president of The New School, a university in New York City. In May 2010, he was selected to become the head of the Motion Picture Association of America. The MPAA, however, could not reach an agreement with him and chose former Connecticut Senator Chris Dodd instead.

In 2012, Kerrey sought election to his old Senate seat to succeed his successor, the retiring Democratic incumbent Ben Nelson. He lost to Republican nominee Deb Fischer.

In 2013, Kerrey joined the Carmen Group lobbying firm.

Kerrey is a co-chair for the advisory board of Issue One, an organization that describes its mission as "fighting for real solutions to the problem of money in politics". In 1987, Kerrey was elected to the Common Cause National Governing Board.
