Hudson's Adventure Island (高橋名人の冒険島 Takahashi Meijin no Bōken Jima?, "Master Takahashi's Adventure Island"), also known simply as Adventure Island, is a side-scrolling platform game produced by Hudson Soft that was first released in Japan for the Famicom and MSX on September 12, 1986. It was later released in North America for the Nintendo Entertainment System on September 1988 and in the PAL region in 1992 under the title of Adventure Island Classic. Adventure Island is an adaptation of the arcade game Wonder Boy, originally published by Sega for developer Escape (now known as Westone Bit Entertainment). Adventure Island was followed by a series of sequels that were independently developed by Hudson Soft.

Master Takahashi's Adventure Island IV is the fourth and final Adventure Island game released for the Famicom. It bears the distinction of being the final official Family Computer game in Japan and was never officially released for the international market. Unlike previous entries in the Adventure Island series, Bōken Jima IV plays less like a straight platformer and more of an action/adventure platformer, similar to the later Wonder Boy games.

Adventure Island 3 (高橋名人の冒険島Ⅲ Takahashi Meijin no Bōken Jima Surī?, lit. "Great Takahashi's Adventure Island III") is a side-scrolling platform game published by Hudson Soft that was originally released for the Nintendo Entertainment System in 1992. It is the third game in the Adventure Island released for the NES, following Adventure Island II. A portable version was also released for the Game Boy in 1993 titled Adventure Island II: Aliens in Paradise, which was retitled in the West due to the fact that the previous Adventure Island game had its number left out from its Game Boy port.
