Rocky Graziano, born Thomas Rocco Barbella in New York City (January 1, 1922–May 22, 1990), was an American boxer. Graziano was considered one of the greatest knockout artists in boxing history, often displaying the capacity to take his opponent out with a single punch.

Graziano fought briefly as an amateur, winning the New York AAU Metropolitan Championship.

In 1948 the National Boxing Association indefinitely suspended Graziano in all parts of the world under NBA supervision, announced President Abe Green, following similar action by the California State Athletic Commission. This was due to Graziano's "running out" on a scheduled Dec. 1 bout with Fred Apostoli. The suspension covered all of the American states, Great Britain, the European Boxing Federation, Cuba, Mexico, and Canada. Almost two years earlier, Graziano had been suspended by the NYSAC for failure to report an alleged bribe attempt. Boxing promoter Ralph Tribuani got Graziano a license in Delaware, where the allegations were perceived as ridiculous. This led to the reinstatement of Graziano by both the NBA and NYSAC and Rocky’s return to prosperity.
