Bronislau "Bronko" Nagurski (November 3, 1908 – January 7, 1990) was a Canadian-American professional football player who was a fullback and defensive tackle in the National Football League (NFL). Renowned for his strength and size, Nagurski was considered to be the most dangerous fullback of his era, and was also a successful professional wrestler, recognized as a multiple-time World Heavyweight Champion.

Nagurski became a college football standout playing both tackle on defense and fullback on offense for the Minnesota Golden Gophers from 1927 to 1929, selected a consensus All-American in 1929 and inducted into the College Football Hall of Fame in its inaugural year of 1951. His professional career with the Chicago Bears, which began in 1930 and ended on two occasions in 1937 and 1943, also made him an inaugural inductee into the Pro Football Hall of Fame in 1963.
