Joy Ethel Batchelor (12 May 1914 – 14 May 1991) was an English animator, director, screenwriter, and producer. She married John Halas in 1940 and subsequently co-established Halas and Batchelor cartoons, whose best known production is the animated feature film Animal Farm (1954), which made her the first woman director of an animated feature since Lotte Reiniger. Together they created over 2000 shorts/films, and produced roughly 70 propaganda pieces during World War II for the British government. She helped co-write, write, animate, produce, and direct many of their productions.

One of her projects as an art director was Cinerama Holiday (1955). Joy directed and wrote Ruddigore (1967), a television-film adaptation of W.S. Gilbert's opera of the same name, which became the first opera to be adapted into an animated film. She later worked in television, directing series, including animated shows like The Jackson 5ive (1971). Batchelor died on 14 May 1991, just two days after her 77th birthday.
