The KO-D (King of DDT) 6-Man Tag Team Championship (Japanese: KO-D6人タッグ王座, Hepburn: KO-D Roku-nin Taggu Ōza) is a professional wrestling championship owned by the DDT Pro-Wrestling (DDT) promotion.

Like most professional wrestling championships, the title is won as a result of a scripted match.

DDT Pro-Wrestling (DDT) had previously promoted matches for the Jiyugaoka 6-Person Tag Team Championship, the Sea Of Japan 6-Person Tag Team Championship and the UWA World Trios Championship, but although all three titles were last held by DDT wrestlers, none of them have been seen in the promotion since the end of 2010.

[8][9] The inaugural KO-D 6-Man Tag Team Champions were determined on January 12, 2013, in a four-team single-elimination tournament, which saw Team Dream Futures (Keisuke Ishii, Shigehiro Irie and Soma Takao) defeat Team Shiro (Akito, Makoto Oishi and Sanshiro Takagi) in the finals to win the title.

[2] As of March 5, 2025, there have been 56 reigns shared among 64 wrestlers and 41 teams.
