Tōni Station (唐丹駅, Tōni-eki) was a railway station on the Sanriku Railway Company’s Rias Line located in the city of Kamaishi, Iwate Prefecture, Japan.

Tōni Station has a single elevated island platform.

Kamaishi, Miyako and Kuji Tōni Station opened on 1 April 1984.

During the 11 March 2011 Tōhoku earthquake and tsunami, part of the tracks on the Minami-Rias Line were swept away, thus suspending services.

The line resumed operations on 3 April 2013 between Sakari and Yoshihama.
