Mitsubishi G4M (japonsko: 一式陸上攻撃機, 一式陸攻 Išiki rikujō kōgeki ki, Išikirikkō; zahodna oznaka: Betty; vzdevek: hamaki - cigara) je bil japonski dvomotorni srednje težki bombnik iz 2. svetovne vojne. G4M je bil sposobno letalo, bil je lahek in je imel velik dolet, je pa bil skoraj povsem brez zaščite (oklepa) za posadko. To je bilo tudi osebno letalo velikega japoskega admirala Isorokuja Jamamota. V njem je 18. aprila 1943 na otoku Bougainville v Solomonovem otočju po sestrelitvi tudi umrl. Ostanki njegovega letala so še danes vidni v džungli, kjer je strmoglavilo.
