Tales of the World: Narikiri Dungeon 3 (テイルズオブザワールド なりきりダンジョン3, Teiruzu Obu za Waarudo Narikiri Danjon 3) is a spin-off from the Tales RPG series made by Namco. The game was released exclusively in Japan for the Game Boy Advance on January 6, 2005. Tales of the World: Narikiri Dungeon 3's characteristic genre name is Cosplay S-RPG (コスプレS-RPG, Kosupure S-RPG).

Tales of the World: Narikiri Dungeon 3 is a turn-based tactical RPG as well as a real-time RPG. Battles take place in enclosed areas that include ally parties and enemy units. Players move parties (consisting of three characters each) by selecting the sprite of the party's player-controlled character, then selecting the target location on the map. The limit of where the party can travel is indicated by dots between the target destination and the starting point of the party. When the dots are gray, the party can move to that location, as long as an obstacle does not block them. If it is red, then the target is out of range. The player can alter the destination of the party at any time during the player's turn. When the player ends the turn, all ally parties will move simultaneously. When one of the players' parties comes in contact with an enemy party, the player engages in a LMBS-style battle. In a typical RPG fashion, players level up their party members to gain stat increases. Like many Tales games, Narikiri Dungeon 3 includes the aspect of cooking: players can use acquired ingredients to prepare meals that affect party members, like replenishing HP, or temporarily gaining a certain stat in battle.
