The Buck Buchanan Award is awarded annually to the most outstanding defensive player in the Division I Football Championship Subdivision (formerly Division I-AA) of college football, and was first given in 1995 after the Walter Payton Award was designated solely for offensive players. It was named in honor of Pro Football Hall of Fame defensive tackle Buck Buchanan, who starred at Grambling State University. Buchanan was an All-American defensive lineman and the first overall pick in the 1963 American Football League (AFL) Draft by the Kansas City Chiefs.
