Saiyuki Gaiden (Japanese: 最遊記外伝, Hepburn: Saiyūki Gaiden) is a Japanese manga series that serves as a prequel to the Saiyuki series Kazuya Minekura wrote and illustrated. Saiyuki Gaiden began serialization in Square Enix's shōnen manga magazine Monthly GFantasy from May 1999 to February 2003 and continued serialization in Ichijinsha's josei manga magazine Monthly Comic Zero Sum from November 2003, and was then transferred to the publisher's shōjo manga Comic Zero Sum WARD. Serialization finished in May 2009, with its chapters collected in four tankōbon volumes. The manga tells a story that occurs 500 years before the main story.

Sentai Filmworks licensed a three-part original video animation (OVA) adaptation that aired from March to November 2011. A special edition titled Saiyuki Gaiden: Kouga no Shou was released in April 2013. Sentai Filmworks released in North America a "Complete Collection" Blu-ray edition that compiled the series into a two-hour feature-length motion picture in September 2022.
