Wario's Woods is a puzzle video game developed by TEC and published by Nintendo for the Nintendo Entertainment System. It was released in Japan and North America in 1994 and Europe in 1995. A spin-off of the Mario series, players control Toad in his mission to defeat Wario, who has taken control of the Peaceful Woods. Gameplay revolves around clearing each level by using bombs to destroy groups of enemies. The game also features a multiplayer mode that allows two players to compete against each other.

Wario's Woods is noteworthy for being the last officially-licensed NES game in North America, released at the end of the console's lifespan. It is also the only NES game to receive a rating from the Entertainment Software Ratings Board (ESRB), which was inducted several months before the game's release. In Japan, the game was released alongside a re-release of The Legend of Zelda to coincide with the release of the AV Famicom.

Wario's Woods has been re-released several times for other platforms, such as the Satellaview and the Wii Virtual Console. The game received mixed to positive reviews from critics, who praised its gameplay, design, and multiplayer mode; though some believed it was not as refined as Nintendo's previous puzzle games like Dr. Mario, and lacked depth and enough content to keep players engaged.
