Bionicle: Matoran Adventures is a 2002 platform game based on Lego's Bionicle line of constructible action figures. It was developed by Argonaut Games and co-published by Electronic Arts and Lego Interactive for the Game Boy Advance. The player controls Matoran and Turaga characters, who must work together to repel the invasion of Bohrok, insect-like robots that threaten the island of Mata Nui.

The game features six levels and three boss battles. Matoran can jump higher and throw discs, while Turaga can activate switches and destroy obstacles; players can switch between the two during gameplay depending on need, similar to the 1993 video game The Lost Vikings. Additional characters can be unlocked by collecting mask pieces scattered throughout levels. Matoran Adventures received mixed reviews from critics. The gameplay and charm were praised by some, with some comparing it favorably to The Lost Vikings, while its short length and lack of creativity were more poorly received.

Matoran Adventures is set on the fictional island of Mata Nui, a "tropical paradise" with six elementally-themed regions. Each region (the aquatic region of Ga-Wahi, the jungle region of Le-Wahi, the icy and mountainous region of Ko-Wahi, the subterranean region of Onu-Wahi, the desert region of Po-Wahi, and the volcanic region of Ta-Wahi) makes up one of the game's six levels. The game follows a Matoran as they attempt to repel the invasion of the insect-like Bohrok swarm. In the official Bionicle story, the Bohrok are instead defeated by the Toa.

Matoran Adventures is a side-scrolling platform game with puzzle elements. The player can choose from three difficulty levels (Easy, Medium, and Hard). The game utilizes a character-swapping mechanic similar to The Lost Vikings (1993). As needed, the player can swap between Matoran and Turaga to advance past obstacles. The Matoran character can jump and throw discs to combat enemies, while the Turaga character can break obstacles using their elemental power and activate switches. The Turaga character cannot jump as high as the Matoran. The game features six levels and three boss encounters. The Matoran character's disc is upgraded as the game progresses. Pieces of masks are scattered throughout each level. By gathering all of the pieces of a particular mask, they gain the ability to play as a different Matoran character. One Matoran character, Kongu, is available from the start; the other five Matoran characters must be unlocked.
