Wario's Woods (Japanese: ワリオの森, Wario no Mori) is a puzzle game released for both the NES and SNES in 1994. It is also one of the many playable NES games in Animal Crossing for the Nintendo GameCube; it can be obtained through using interacting with an islander using the game's Animal Island mode on the Game Boy Advance.

The NES version is notable for being not only the last first-party game produced for the console, but the last game with Nintendo's official license to be released for the platform in North America. As a result of its late release, it was the only game in the NES library to have an official rating by the ESRB, being rated K-A for Kids to Adults. The SNES version carries the same rating. The game is known for being one of only two games that have Toad as the main starring protagonist (the other being Kinopio Live for the SNES's Japan-only Satellaview add-on), though Captain Toad: Treasure Tracker's main character is Captain Toad, a similar character. Wario's Woods was released to the Wii Virtual Console on November 19, 2006 in America, and December 7-12, 2006 in the PAL regions and Japan. The NES version was later released on the Nintendo 3DS Virtual Console and Wii U Virtual Console in 2013, where it received the E for Everyone rating, and was made available to Nintendo Switch Online members from December 12, 2018.
