The Rings of Power are magical artefacts in J. R. R. Tolkien's legendarium, most prominently in his high fantasy novel The Lord of the Rings. The One Ring first appeared as a plot device, a magic ring in Tolkien's children's fantasy novel, The Hobbit; Tolkien later gave it a backstory and much greater power. He added nineteen other Great Rings, also conferring powers such as invisibility, that it could control, including the Three Rings of the Elves, Seven Rings for the Dwarves, and Nine for Men. He stated that there were in addition many lesser rings with minor powers. A key story element in The Lord of the Rings is the addictive power of the One Ring, made secretly by the Dark Lord Sauron; the Nine Rings enslave their bearers as the Nazgûl (Ringwraiths), Sauron's most deadly servants.

Magic in Middle-earth is the use of supernatural power in J. R. R. Tolkien's fictional Middle-earth. Tolkien distinguishes ordinary magic from witchcraft, the latter always deceptive, stating that either type could be used for good or evil.
