Phran Kratai (Thai: พรานกระต่าย, pronounced [pʰrāːn krā.tàːj]) is the northernmost district (amphoe) of Kamphaeng Phet province, central Thailand.

A hunter (phran) surveyed southward to seek a strategic location to build a frontier city for Sukhothai Kingdom.

When he spent the night in the area of the district, he found a golden haired rabbit (kratai) in front of a cave, which however quickly disappeared.

The hunter reported his discovery to the King of Sukhothai and volunteered to catch the rabbit.

Neighboring districts are (from the southeast clockwise): Lan Krabue, Sai Ngam, Mueang Kamphaeng Phet, Kosamphi Nakhon of Kamphaeng Phet Province; Mueang Tak of Tak province; Ban Dan Lan Hoi and Khiri Mat of Sukhothai province.
