Eye of the Beholder is a computer game released in 1991. It was developed by Westwood Associates and published by Strategic Simulations, Inc. for DOS, Amiga, Sega CD, SNES and PC-9800. It is the first game of the Eye of the Beholder series.

Eye of the Beholder featured a first-person perspective in a three-dimensional dungeon, very similar to the earlier Dungeon Master. The player controls four characters, initially, using a point-and-click interface to fight monsters. This can be increased to a maximum of six characters, by resurrecting one or more skeletons from dead non-player characters (NPC), or finding NPCs that are found throughout the dungeons. The possibility to increase the size of the player's party through the recruiting of NPCs was a tradition in all of the Eye of the Beholder series. It was also possible to import a party from Eye of the Beholder into Eye of the Beholder II: The Legend of Darkmoon or from Eye of the Beholder III: Assault on Myth Drannor; thus, a player could play through all three games with the same party.
