The 2012 FIM MotoGP World Championship was the premier class of the 64th Fédération Internationale de Motocyclisme (FIM) Road Racing World Championship season, the highest level of competition in motorcycle road racing. Casey Stoner started the season as the defending World Champion, while Honda was the defending Manufacturers' Champion.

In the premier MotoGP class, the championship battle revolved around Yamaha rider Jorge Lorenzo and Honda pairing Dani Pedrosa and defending champion Stoner. Lorenzo won four of the first six races to be held in the campaign to open up an advantage over Stoner, before he was taken out of the Dutch TT on the first lap by Álvaro Bautista; Stoner won the race to eradicate the points lead. In the next race, Stoner crashed out of the German Grand Prix on the final lap and allowed Pedrosa to take his first win of the season. Stoner struggled in the next few races – despite a victory at the United States Grand Prix – with his championship challenge ended by a qualifying crash at Indianapolis. After ankle surgery, he returned to the series and won his final race of his career at his home race, the Australian Grand Prix, for the sixth successive season. Pedrosa went on a run of five victories in six races, with the streak being interrupted by a first-lap crash at Misano, where he was taken out by Héctor Barberá. Lorenzo finished second to Pedrosa on each occasion that he had won, and he took advantage of Pedrosa's accident to win at Misano. Lorenzo ultimately won the title with a second-place finish to Stoner in Australia, after Pedrosa had crashed out of the lead early on.

Changes Class changes The MotoGP class saw the introduction of engines with in capacity, with a limit of 4 cylinders and a maximum cylinder bore.

Claiming Rule Teams In 2012 the MotoGP class saw the introduction of Claiming Rule Teams (CRT) to allow for participation by independent teams with lower budgets. CRTs were given twelve engines per rider, six more than the other teams and more fuel – instead of – but were subject to a factory team buying, or "claiming", their engines for €15,000, or €20,000 with the transmission. The sport's governing body received applications from sixteen new teams looking to join the MotoGP class.
