A dungeon crawl is a type of scenario in fantasy role-playing games (RPGs) in which heroes navigate a labyrinth environment, battling various monsters, avoiding traps, solving puzzles, and looting any treasure they may find. Video games and board games which predominantly feature dungeon crawl elements are considered to be a genre.

A dungeon is a room or cell in which prisoners are held, especially underground. Dungeons are generally associated with medieval castles, though their association with torture probably derives more from the Renaissance period. An oubliette or bottle dungeon is a basement room which is accessible only from a hatch or hole in a high ceiling.
