Lady and the Tramp is a 1955 American animated film produced by Walt Disney and released to theaters on June 22, 1955, by Buena Vista Distribution. The 15th animated film in the Walt Disney Animated Classics series, it was the first animated feature filmed in the CinemaScope widescreen film process. The story centers on a female anthropomorphic American Cocker Spaniel named Lady who lives with a refined, upper middle-class family, and a male stray mutt called the Tramp. A direct-to-video sequel, Lady and the Tramp II: Scamp's Adventure, was released in 2001.

On Christmas morning 1909, Jim Dear gives his wife Darling a cocker spaniel puppy that they name Lady. Lady enjoys a happy life with the couple and with a pair of dogs from the neighborhood, a Scottish Terrier named Jock and a bloodhound named Trusty. Meanwhile, across town by the railway, a stray mutt, referred to as The Tramp, lives life from moment to moment, be it begging for scraps from the local Italian restaurant or protecting his fellow strays Peg (a Lhasa Apso) and Bull (an English bulldog) from the local dog catcher.
