The IMGP World Heavyweight Championship (Japanese: IMGP世界ヘビー級王座, Hepburn: IMGP Sekai Hebī-kyū Ōza) is an inactive professional wrestling championship in the Japanese promotion Muscle (マッスル, Massuru), a sub-brand of DDT Pro-Wrestling. IMGP is the acronym of International Muscle Grand Prix and a parody of New Japan Pro-Wrestling's governing body, the International Wrestling Grand Prix.

The championship was introduced in late 2006 and has been represented by a belt resembling the second IWGP Heavyweight Championship design. Since Atsushi Maruyama won the title in 2015, it has never been defended nor has it been officially deactivated.
