Willy McBean and His Magic Machine is a 1965 stop motion animated time travel film produced by Arthur Rankin, Jr. and Jules Bass' Videocraft International (now Rankin/Bass Productions) in the United States and Dentsu Motion Pictures in Japan. It was presented by Marshall Naify, released by Magna Pictures Distribution Corporation on June 23, 1965.

The film tells the story of Willy McBean, a young schoolboy who teams up with an anthropomorphic monkey named Pablo to prevent the villainous professor Rasputin Von Rotten from changing the history of the world, using the newly created and duplicated "magic" time machine.

Written, produced and directed by Arthur Rankin, Jr., with Jules Bass and Larry Roemer as associate producers, the film uses a team of voice actors under the soundtrack recording supervision of Bernard Cowan in Canada, including Larry D. Mann as Von Rotten Billie Mae Richards as Willy And Paul Soles as Pablo the Monkey. Tadahito Mochinaga supervises the "Animagic" stop motion process at MOM Productions in Japan, the same team behind the animation for The New Adventures of Pinocchio (1960–61) and Rudolph the Red-Nosed Reindeer (1964).
