Baí Zé (simplified Chinese: 白泽; traditional Chinese: 白澤; Wade–Giles: Pai Tse), or hakutaku (白澤) in Japanese, is a fantastic beast from Chinese legend. Its name translates literally to "white marsh".

The Baí Zé was first encountered by the emperor Huáng Dì. Supposedly, the beast dictated a guide to Huáng Dì, telling the forms and habits of all 11,520 supernatural creatures in the world, plus how to overcome their hauntings and attacks. The information was transcribed in a book called the Bái Zé Tú (白泽图/白澤圖). Although the book no longer exists in its intact form, many fragments of it have survived through other texts.

A similar creature, the kutabe, is described in Japan as a "bovine or monstrous felid creature with nine eyes and six horns, arranged in sets of three and two on both its flanks and its man-like face." It is also depicted with the body of a lion, eight eyes, and a horn or multiple horns on its head.
