Sleeping Beauty (French: La belle au bois dormant, or The Beauty in the Sleeping Forest; German: Dornröschen, or Little Briar Rose), also titled in English as The Sleeping Beauty in the Woods, is a fairy tale about a princess cursed by an evil fairy to sleep for a hundred years before being awakened by a handsome prince. A good fairy, knowing the princess would be frightened if alone when she wakes, uses her wand to put every living person and animal in the palace and forest asleep, to waken when the princess does.

The earliest known version of the tale is found in the narrative Perceforest, written between 1330 and 1344. Another was published by Giambattista Basile in his collection titled The Pentamerone, published posthumously in 1634 and adapted by Charles Perrault in Histoires ou contes du temps passé in 1697. The version collected and printed by the Brothers Grimm was one orally transmitted from the Perrault.

The Aarne-Thompson classification system for fairy tales lists Sleeping Beauty as a Type 410: it includes a princess who is magically forced into sleep and later woken, reversing the magic. The fairy tale has been adapted countless times throughout history and retold by modern storytellers across a variety of media.
