Triangle Derby I was the first annual round-robin six-woman tag team tournament event promoted by World Wonder Ring Stardom under the "Triangle Derby" branch. The event took place between January 3 and March 4, 2023, with limited attendance due in part to the ongoing COVID-19 pandemic at the time (until January 30). It also represented the first major event promoted by Stardom in 2023.
The Triangle Derby is a professional wrestling tournament held annually by Stardom. It is currently disputed as a round-robin tournament with teams of three wrestlers split into two pools. Contrary to most round-robin style tournaments, teams from the same pool don't face each other. Instead, each team faces all teams from the opposite pool. Matches are fought with a 15-minute time limit. A win is worth two points and a draw is worth one point. The top two teams from each pool will advance to a final single-elimination bracket, consisting of semifinals and finals.
The tournament featured professional wrestling matches that resulted from scripted storylines, where wrestlers portrayed villains, heroes, or less distinguishable characters in the scripted events that built tension and culminated in a wrestling match or series of matches. The event's official press conference took place on December 16, 2022, and was broadcast live on Stardom's YouTube channel.
This is a list of participants including the champions during the event. The tournament featured fourteen teams formed by a total of forty-two wrestlers, divided into two distinctive blocks with the two highest placed teams of their respective blocks moving on to the semifinals.
