Professional boxing, or prizefighting, is regulated, sanctioned boxing. Professional boxing bouts are fought for a purse that is divided between the boxers as determined by the contract. Most professional fights are supervised by a regulatory authority to guarantee the fighters' safety. Most high-profile bouts obtain the endorsement of a sanctioning body, which awards championship belts, establishes rules, and assigns its own judges and referees.

In contrast with amateur boxing, professional bouts are typically much longer and can last up to twelve rounds, though less significant fights can be as short as four rounds. Protective headgear^[1] is not permitted, and boxers are generally allowed to take substantial punishment before a fight is halted. Professional boxing has enjoyed a much higher profile than amateur boxing throughout the 20th century and beyond.
