Bonus dungeon (エクストラダンジョン, Ekusutora Danjon?, lit. Extra Dungeon), also known as secret dungeon or optional dungeon, is an optional location that is usually much more difficult than the main game with enemies that are much higher level than on other parts of the game. These dungeons are considered sidequests and often contain the most powerful equipment and, sometimes, summons that can only be obtained by completing the dungeon. The boss fought at the end of a bonus dungeon is often a superboss.

A game can have multiple bonus dungeons. Bonus dungeons are common features added to remakes of older games, to give experienced players new material to test their skills against, and to make the remake more lucrative purchase for people who have already completed an earlier version of the game.
