Yasunori Katō (加藤 保憲, Katō Yasunori) is a fictional character, the protagonist of the Japanese historical fantasy series Teito Monogatari, created by Hiroshi Aramata. He first appeared in a 1983 issue of a science fiction magazine published by Kadokawa Shoten but gained more widespread attention with successive publications as well as his cinematic debut, and has since gone on to be referenced frequently in Japanese popular culture. His character is generally associated with onmyōdō mysticism since Teito Monogatari was one of the first novels to popularize the art in modern Japanese fiction.

In Japanese, he is commonly referenced with the prefix "Majin" (魔人, Majin; 'Demon Man') due to his incredible superhuman abilities and near immortality.
