Ikkyū-san (Japanese: 一休さん, pronounced [ik̚kʲɨᵝːsã̠ɴ]) is a Japanese historical comedy anime series produced by Toei Animation, based on the recorded early life of Zen Buddhist monk Ikkyū during his stay at Ankoku-ji Temple.

The Ikkyū-san anime was directed by Kimio Yabuki and written by Makoto Tsuji, Tadaki Yamazaki, Hisao Okawa, Tatsuo Tamura, Hiroyasu Yamaura and Keisuke Fujikawa. It aired on TV Asahi from October 15, 1975 to June 28, 1982.

The series was received by all ages in Japan and throughout Asia, as it is mostly non-violent. Even when violence appears, it is usually presented in a mild or necessary way (for example, there are occasional references to the Ōnin War). In 1976, there was also a theatrical film released as part of the Toei Manga Matsui film festival in the summer of that year. A film retelling of the Mischievous Princess film was released in 2014.
