Disney's Sleeping Beauty, 1959
Disney's animated film Sleeping Beauty was the last fairy tale produced by Walt Disney before his death. Due to the movie's poor box office numbers, the studio's next Disney princess film wasn't until The Little Mermaid in 1989.
The princess's name is Aurora, the same as in Tchaikovsky's ballet. And this film introduces Disney's most evil villain, Maleficent (derived from a Latin word meaning "harmfully malicious"), who famously transforms into a dragon during the climax of the story.
