Jack and the Witch (少年ジャックと魔法使い, Shōnen Jakku to Mahōtsukai, lit. 'The Boy Jack and the Witch') is a Japanese animated fantasy adventure feature film, the 10th cinema feature produced by Tōei Animation (then Tōei Dōga), released in Japan in 1967. It was developed by Jirō Sekimasa, Seiichi Moro and Takeshi Ariga, written by Shin'ichi Sekizawa and Susumu Takaku and directed by Taiji Yabushita and has an essentially original story, though one which alludes in structure and character names to the Jack tales and Beowulf, both of English folklore. A working title for the film was Fushigina Sekai no Daibōken (ふしぎな世界の大冒険, "Great Adventure in a Strange Land"). The animation director is Akira Daikuhara.

It is one of a number of Tōei Dōga features licensed by the television division of American International Pictures and localised by Titan Productions, Jack's English-dubbed version being directed by Peter Solmo and made available for syndication starting in 1969. Corinne Orr, of Speed Racer fame, is the voice of Allegra in the English-language version.
