Eye of the Beholder II: The Legend of Darkmoon is a 1991 role-playing video game and the sequel to the first Eye of the Beholder. It used a modified version of the first game's engine, added outdoor areas and greatly increased the amount of interaction the player had with their environment, along with substantially more role-playing aspects to the game. A sequel, Eye of the Beholder III: Assault on Myth Drannor, was released in 1993.

Much of the game remains within the confines of the temple, where the player is allowed to roam freely between locations once inside. The game itself features the catacombs beneath the Temple Darkmoon, the upper levels of the temple, and its three towers; silver, azure and crimson. Like the first game in the series, Eye of the Beholder II was also ported to the Amiga computer.
