Hiraoka Station (平岡駅, Hiraoka-eki) is a railway station on the Iida Line in the village of Tenryū, Shimoina, Nagano Prefecture, Japan, operated by Central Japan Railway Company (JR Central).

Hiraoka Station is served by the Iida Line and is 93.8 kilometers from the starting point of the line at Toyohashi Station.

The station consists of a single ground-level island platform connected to the station building by a level crossing.

With the privatization of Japanese National Railways (JNR) on 1 April 1987, the station came under the control of JR Central.
