The is an annual professional wrestling tournament that was held for seven editions from 2018 to 2023. DDT Pro-Wrestling (DDT) first hosted it from 2018 to 2020, and CyberFight hosted it as a DDT-branded event from 2021 to 2023. Unlike the annual King of DDT Tournament, which is a single-elimination tournament, the D-Oh Grand Prix was round-robin. Like the King of DDT, however, the winner of the D-Oh Grand Prix received a shot at the KO-D Openweight Championship.

History The tournament was created by DDT producer Danshoku Dino in August 2017 and later confirmed in November.

After the first edition was held in January 2018, the second edition had to be held in December 2018 while retaining the name "D-Oh Grand Prix 2019". This offset between the tournament title and the year it was actually held persisted until 2021 where the tournament (held between November and December 2021) was entitled "D-Oh Grand Prix 2021II".

Shuji Ishikawa is the inaugural winner of the tournament; Konosuke Takeshita is the only two-time winner.

Rules The matches were fought to one fall with a 30 minutes time limit. The final had no time limit. The participants were divided into two blocks, A and B, and fought in a round-robin using a points system; two points for a victory, one point for a draw, and zero points for a loss. The winners from the two blocks went on to fight in the final to decide the D-Oh Grand Prix winner. The D-Oh Grand Prix winner, assuming they did not already hold the KO-D Openweight Championship, obtained first contendership to the title and received a title shot.
