The Legend of Kyrandia: Book One is a 2D point-and-click adventure game, and the first game in the Fables & Fiends series. It was developed by Westwood Studios and published by Virgin Games in August 1992. Players take on the role of a young prince who must end the tyrannical chaos of an evil court jester in his kingdom. The game makes use of a simple interface system that allows the player to interact with objects and people, while solving various puzzles using a variety of items and special abilities.

The game proved a commercial success and was praised for many of its elements. Its success spawned two sequels: The Legend of Kyrandia: Hand of Fate in 1993; and The Legend of Kyrandia: Malcolm's Revenge in 1994. GOG.com released an emulated version for Microsoft Windows and Mac OS X in 2013.

The Legend of Kyrandia utilizes a point-and-click interface which is more simple than similar games of its era, which instead relied on more complex multi-action interfaces. In the game, players can click on anything to examine and interact with objects, items in a scene and people. Any objects that can be taken can be stored in a simple inventory, with the player able to carry a set amount on their character, but able to drop objects within a scene for later collection or removal. The game features a variety of puzzles and scenes to explore, though also features hazardous obstacles, traps, and moments that can incur death; being killed automatically ends the game, and forces players to start a new game or reload from the last save they made. One of the more unique elements in the game is a special amulet with colored gems, each of which can be used to solve a puzzle with a special magic.
