The World Heavyweight Championship is a professional wrestling world heavyweight championship in the Japanese promotion Pro Wrestling Zero1. It is Zero1's top singles title. It was first introduced on December 15, 2007 when Zero1 ended their relationship with the AWA Superstars of Wrestling. The AWA Superstars of Wrestling Champion at the time, Masato Tanaka, was then recognized as the first Zero1 World Heavyweight Champion. To this day, Zero1 continues to use the AWA title belt, which reads "AWA World Heavyweight Wrestling Champion", to represent their world heavyweight championship.

There have been a total of 22 recognized champions who have had a combined 36 official reigns. Junya Matsunaga is the current champion in his seventh reign. He defeated Masato Tanaka to win the title at the ZERO1 25th Anniversary Show on April 3, 2026. This is his first title reign, and at the time was the Co-Holder of the Intercontinental Tag Team Championship (Zero1) with Tsugutaka Sato, becoming a Double Champion.
