James Gordon "Bo" Gritz (/ˈɡraɪts/; born January 18, 1939) is a former United States Army Special Forces officer who served in the Vietnam War. His post-war activities – notably attempted POW rescues in conjunction with the Vietnam War POW/MIA issue – have proven controversial.

Gritz may be most notable for his two United States presidential campaigns in association with the white nationalist America First party in 1988 and 1992. In 1988, Gritz ran as vice president with former Grand Wizard of the Ku Klux Klan David Duke. A vocal advocate for the re-institution of racial segregation in states that pass laws to allow it, Gritz ran in 1992 under the slogan: "God, Guns and Gritz," and published an isolationist political manifesto entitled "The Bill of Gritz". Among other things, the "Bill of Gritz" called for the complete closing of the border with Mexico, and the dissolution of the Federal Reserve. Gritz lives near Sandy Valley, Nevada, with his wife Judy.
