Dragon Quest Walk^[1] is a geolocation-based role-playing video game developed by COLOPL and published by Square Enix for Android and iOS. It is a free-to-play entry in the Dragon Quest series and was released in Japan on 12 September 2019.

The gameplay of Dragon Quest Walk is centered around interaction with various real-world locations in-game, with various monsters and characters from the Dragon Quest series being in the game. Players could battle monsters in order to improve their character and obtain items, or in order to advance quests. The quests system in the game require players to walk towards certain destinations in real life, which would unlock enemies or interactions with in-game characters. Various locations in the game would also restore the player character's hit points.^[2] The battles with monsters involve the player character, or their party with other players, engaging with one or more monsters. Once the battle is completed, players may receive items which could be equipped on their characters in order to improve their skills.^[3][4] As with other games in the JRPG genre or in the Dragon Quest series, players may opt to automatically resolve the battle without additional input.^[5] Occasionally, more powerful monsters may appear in the in-game map, which could be fought by up to 12 players simultaneously.^[6]

Within the game, players could also establish "home" locations wherever they would like.^[3] These homes could be customized with various decorations, similar to the MMO Dragon Quest X.^[7]
