Doctor Dolittle is a 1967 American musical comedy film directed by Richard Fleischer and starring Rex Harrison, Samantha Eggar, Anthony Newley, and Richard Attenborough. It was adapted by Leslie Bricusse from the Doctor Dolittle novel series by Hugh Lofting, primarily The Story of Doctor Dolittle (1920), The Voyages of Doctor Dolittle (1922), and Doctor Dolittle's Circus (1924).

The Voyages of Doctor Dolittle is the second of Hugh Lofting's Doctor Dolittle books. Published in 1922, the writing style is aimed at a more mature audience and features more sophisticated illustrations than its predecessor. The novel's scope is vast; it is nearly five times as long as its predecessor and is divided into six parts. It won the Newbery Medal for 1923.
