Mighty Bomb Jack (マイティボンジャック, Maiti Bon Jakku) is a 1986 arcade game that was later released for the Nintendo Entertainment System (NES) in 1987 by Tecmo, and later for the Amiga, Atari ST and Commodore 64. The NES version was released on the Virtual Console on May 7, 2007 for the Wii and on December 6, 2012 for the Nintendo 3DS. It is a sequel to Bomb Jack.

Each level is split into two parts; an action zone and a Royal Palace room. The mechanics and level designs of the Royal Palace rooms are directly lifted from Bomb Jack. Action zones can be split up into several portions, and contain power-ups usually hidden in treasure chests such as money bags, Mighty Coins and Mighty Drinks. Mighty Coins allow Jack to change colors; blue allows Jack to open orange treasure chests, orange allows him to open any treasure chest by simply touching it from the side, and green transforms all enemies on the screen into coins for 5 seconds. Mighty Drinks add 10 seconds to the game's timer. Secret passages can also be found in the action zones, activated by finding a Sphinx in a visible or hidden treasure chest.

To prevent the player from becoming too "greedy", the game automatically sends the player to a Torture Room if they obtain more than 9 Mighty Coins or 99 seconds on the game's timer. The only way to escape a Torture Room without losing a life is to complete a number of jumps, which are counted down on the screen. Once the player exits the torture room, Jack automatically loses all Mighty Coins, the timer is reset to 60 seconds, and the game recommences from the beginning of the current level.
