The Ibi River (揖斐川, Ibi-gawa) is a tributary of the Kiso River located in Gifu and Mie Prefectures in Japan. Along with the Nagara and Kiso rivers, the Ibi is the third of the Kiso Three Rivers of the Nōbi Plain. It is one of Japan's first-class rivers.[citation needed] The former Tōkaidō post station of Kuwana-juku was located on the western banks of this river during the Edo period.
