Dungeon (originally published as Dungeon: Adventures for TSR Role-Playing Games) was one of the two official magazines targeting consumers of the Dungeons & Dragons role-playing game and associated products; Dragon was the other.

Dungeon was first published by TSR, Inc. in 1986 as a bimonthly periodical. It went monthly in May 2003 and ceased print publication altogether in September 2007 with Issue 150. Starting in 2008, Dungeon and its more widely read sister publication, Dragon, went to an online-only format published by Wizards of the Coast. Both magazines went on hiatus at the end of 2013, with Dungeon #221 being the last issue released.
