Qix Adventure is a 1999 video game developed by Coconuts Japan Entertainment and published by Taito for the Game Boy Color. An English port of the game was developed by Evolution Entertainment for the United Kingdom in 2000. The game is a puzzle game based on the 1981 Taito title Qix, with additional story elements.

Similar to Qix, Qix Adventure is a puzzle game in which players draw a line to enclose areas of the screen, with the goal of enclosing 75% of the screen as the space fills up with boxes, whilst avoiding moving enemies, Qix and Sparx, that hinder the player's progress. The game features three modes of play. In 'Treasure' mode, the game requires the player to capture enemies by boxing them in and claiming the treasures they leave behind, providing additional opponents, bonus items and score multipliers. In this mode, players can also view collected treasure and use them to decorate a room. "Original" mode follows the traditional rules of Qix. 'Battle' mode allows two players with one Game Pak or a Game Link Cable to compete against each other.
