The Stardom 5 Star Grand Prix is a
professional wrestling tournament held each summer by
Stardom. Similar to
Bushiroad-owned male counterpart
New Japan Pro-Wrestling with the
G1 Climax tournament, it is currently held as a round-robin tournament with wrestlers split into two pools. The winner of each pool will compete in the final to decide the winner. As is the case with G1 Climax, a win is two points and a draw is one point for each wrestler. There have been a total of ten editions that gave ten different champions. Seven of the title challenges were unsuccessful while only three were successful.
Io Shirai successfully defended the
World of Stardom Championship against three different tournament winners while
Mayu Iwatani scored the only two defeats, dropping the same title. In 2021, Stardom introduced the World of Stardom challenge rights certificate, in which the winner of 5 Star Grand Prix receives a contract for a future World of Stardom Championship match. Like NJPW's
Tokyo Dome IWGP Heavyweight Championship challenge rights certificate, the contract is kept in a briefcase and can be defended until the title match. ==List of winners==
