The D-Oh Grand Prix (Japanese: D王 GRAND PRIX, Hepburn: Dī Ō Guran Puri) is an annual professional wrestling tournament hosted by the DDT Pro-Wrestling (DDT) promotion. It was created by DDT producer Danshoku Dino in August 2017 and later confirmed in November. Though DDT also runs the annual King of DDT Tournament, the D-Oh Grand Prix is different in that it is round-robin, whereas the King of DDT is a single-elimination tournament. Like the King of DDT however, the winner of the tournament receives a shot at the KO-D Openweight Championship.
