The Great Adventure of Horus, Prince of the Sun (太陽の王子 ホルスの大冒険, Taiyō no Ōji Horusu no Daibōken) is an anime fantasy adventure film released in July 1968. It is the directorial feature film debut of Isao Takahata and was also worked on by Hayao Miyazaki. Horus marked the beginning of their partnership that would last for the next 50 years across numerous animation studios.

The core production team for Horus, Prince of the Sun included Takahata (Director), Yasuo Otsuka (Animation Director), Miyazaki (Scene Design, Key Animation), Yasuji Mori (Key Animation), Reiko Okuyama (Key Animation), and Yoichi Kotabe (Key Animation). This group contributed to designs, story ideas and storyboards; all but Takahata (who is not an animator) contributed to character designs. Akemi Ota, Masatake Kita, and Sadao Kikuchi were the remaining Key Animators, but did not contribute many ideas to the film.

The movie was released straight to television in the United States by AIP-TV under the title The Little Norse Prince.
