The Ironman Heavymetalweight Championship is a professional wrestling championship created and promoted by the Japanese promotion CyberFight in its DDT Pro-Wrestling (DDT) brand. Open to anyone, regardless of gender or DDT employment status, the championship is defended "24/7", as in any time, anywhere, as long as a referee is there to confirm the win. Because of this rule, not only is the championship winnable regardless of gender or number of individuals, it is also available to "unconventional" champions such as animals or inanimate objects, with title changes regularly occurring outside of regular shows, often with videos posted on the promotion's social media accounts. The current champion is Pokotan, who is in its first reign.

DDT Pro-Wrestling is a Japanese professional wrestling promotion based in Shinjuku, Tokyo. Its name stands for Dramatic Dream Team, which was the promotion's official name from 1997 to 2004. Founded in March 1997 by Shintaro Muto, the promotion was eventually bought and managed by Shoichi Ichimiya until December 2005, when Sanshiro Takagi took over as the new president. In 2017, DDT was sold to CyberAgent. Takagi retained his position, while Takahiro Yamauchi took over as the new DDT director.
