The 2019 FIVB Men's World Cup was the 14th edition of the event, contested by the senior men's national teams of the members of the Fédération Internationale de Volleyball (FIVB), the sport's global governing body. The tournament was held from 1 to 15 October 2019 in Japan. That was the first time since 1989 that FIVB decided not to allocate any spots in the Olympics, due to Japan hosting the 2020 Summer Olympics.

The Japan men's national volleyball team represents Japan in international volleyball competitions and friendly matches, governed by Japan Volleyball Association.
