The Heavyweight Championship is a title awarded in professional boxing and mixed martial arts (MMA) to the top fighters in the heavyweight division. This division typically includes athletes who weigh over 200 pounds (90.7 kg). Winning the championship signifies that a fighter is recognized as the best in their weight class, often leading to high-profile matches and significant media attention. In boxing, the WBC, WBA, IBF, and WBO are the major organizations that sanction heavyweight title fights. In MMA, organizations like the UFC also have their own heavyweight championships. Champions defend their titles against challengers, and the title can change hands through knockout, submission, or decision.
