Jacob Henry "Buddy" Baer (June 11, 1915 – July 18, 1986) was an American boxer and later an actor with parts in seventeen films, as well as roles on multiple television series in the 1950s and 1960s.
In 1941, he came extremely close to boxing stardom at Washington's Griffith Stadium, when in the opinion of most ringside officials, Joe Louis gave him a disqualifying late sixth-round hit in a title match that should have made Baer the world heavyweight champion. He lost to Louis in a rematch for the title the following year but remained solidly ranked among the top heavyweights in the early 1940s. In 2003, Baer was chosen for The Ring magazine's list of 100 greatest punchers of all time. He was the younger brother of boxing heavyweight champion and actor Max Baer, and the uncle of actor Max Baer Jr.
