A bucking bull is a bull used in American rodeo bull riding competition. They are usually a Brahman crossed with another breed, weighing 1,500 pounds or more, selected for their tendency to "leap, plunge and spin" when a human is on its back. Circa mid-20th century breeders began selecting bulls for bad temperament, that would buck when ridden. Many of the best bucking bulls trace their lineage to bulls owned by Charlie Plummer of Oklahoma. These are known as Plummer bulls.

Bull riding is a rodeo sport that involves a rider getting on a bucking bull and attempting to stay mounted while the animal tries to buck off the rider.

American Bucking Bull (ABBI) is an organization dedicated to the registration of bucking bulls and establishing the American Bucking Bull as a documented breed of cattle. American Bucking Bull, Inc., is owned by the Professional Bull Riders (PBR) and stock contractors. The organization created a breed registry and manages the registration and certification of American Bucking Bulls. It also keeps records of other breeds of bulls, some of which died out many years ago. It is the largest organization performing these functions. It maintains a genetic DNA database, manages bucking bull pedigrees and encourages the growth of the breed. ABBI also holds competitions for bucking bulls ages 2 through 4. It also has its own magazine, the American Bucking Bull.

Bodacious #J-31 was a bucking bull. He was known throughout the rodeo sport of bull riding as "the world's most dangerous bull." He was also known as "the greatest bull ever to buck." During his rodeo career he was the 1994 and 1995 Professional Rodeo Cowboy Association (PRCA) Bucking Bull of the Year, as well as the 1995 Professional Bull Riders (PBR) World Champion Bull. He and Bruiser are the only bulls who have won bucking bull world championship titles in both organizations. Bodacious is most well known for his serious injury to bull riding icon Tuff Hedeman. Coincidentally, Hedeman is the only rider to win the world champion bull rider title in both organizations as well. Not long after, Bodacious also seriously injured Scott Breding. His owner, Sammy Andrews, then retired Bodacious. In 1999, Bodacious was inducted into the ProRodeo Hall of Fame, and in 2017 into the Bull Riding Hall of Fame. In 2019, the PBR inducted Bodacious into the Brand of Honor, which is part of the PBR’s Heroes and Legends Celebration, the PBR's unique way of honoring outstanding individuals and livestock in the sport of rodeo. For a bucking bull, this is the highest honor he can receive in the sport of bull riding.

Bucking is a movement performed by an animal in which it lowers its head and raises its hindquarters into the air while kicking out with the hind legs. It is most commonly seen in herbivores such as equines, cattle, deer, goats, and sheep. Most research on this behavior has been directed towards horses and cattle.
