Reyman Edward "Bud" Bonar (July 26, 1906 – November 21, 1970) was an American football player and coach from Bellaire, Ohio.
As a senior at Bellaire High School in 1926, Bonar was the football team captain and quarterback.
As the quarterback for Notre Dame under head coach Hunk Anderson, his career highlight occurred when his drop-kick extra point enabled Notre Dame to defeat 9–0 Army by the score of 13–12 on December 2, 1933, in Yankee Stadium.
After graduation, Bonar played one year of professional football in the CFL before becoming an assistant coach at the University of Cincinnati.
Bonar held the position of Bellaire's athletic director when he died of a heart attack in 1970, purportedly while watching a broadcast of the Notre Dame vs. LSU game.
