Adventure Island II, known in Japan as Takahashi Meijin no Bouken Jima II, is a action platforming game released by Hudson Soft in 1990 for the Ninten.

Adventure Island II plays very similarly to its predecessor. This time more emphasis is given to the platforming, while the screen can be scrolled backwards if necessary, giving a more leisurely pace to the game.

New to this game is the addition of dinosaur friends which the player can mount during the stages, these can be found from eggs much like other items and each of them have their own distinct ability. The player can carry these on between stages and store them, being able to select one of them before each stage.
