Mitani Station (三谷駅, Mitani-eki) is a passenger railway station located in the city of Yamaguchi, Yamaguchi Prefecture, Japan.

Some Super Oki limited express trains stop at this station.

The station consists of one ground-level unnumbered island platform connected by level crossing.

With the privatization of the Japan National Railway (JNR) on 1 April 1987, the station came under the aegis of the West Japan railway Company (JR West).

On 16 May 2001, the station building was destroyed in a fire that was thought to have been caused by a short circuit, but JR West initially refused to rebuild it on the grounds of unprofitability.
