Tom and Jerry: The Magic Ring is a 2002 American animated fantasy comedy film. Produced by Warner Bros. Animation and Turner Entertainment Co., it was the first direct-to-video attempt to recapture the style of William Hanna and Joseph Barbera's original film shorts from Metro-Goldwyn-Mayer as well as the final animated collaboration of both Hanna and Barbera, as Hanna died on March 22, 2001. It was directed by James Tim Walker, written by Tim Cahill & Julie McNally, produced by Tom Minton, and edited by Bradford H. Keatts.

A magic ring is a mythical, folkloric or fictional piece of jewelry, usually a finger ring, that is purported to have supernatural properties or powers. It appears frequently in fantasy and fairy tales. Magic rings are found in the folklore of every country where rings are worn. Some magic rings can endow the wearer with a variety of abilities including invisibility and immortality. Others can grant wishes or spells such as neverending love and happiness. Sometimes, magic rings can be cursed, as in the mythical ring that was recovered by Sigurð from the hoard of the worm Fáfnir in Norse mythology or the fictional ring that features in The Lord of the Rings. More often, however, they are featured as forces for good, or as a neutral tool whose value is dependent upon the wearer.
