Matsuiwa Station (松岩駅, Matsuiwa-eki) was a JR East railway station located in the city of Kesennuma, Miyagi Prefecture, Japan. It was destroyed by the 2011 Tōhoku earthquake and tsunami and services have now been replaced by a provisional bus rapid transit line.

Matsuiwa Station was served by the Kesennuma Line, and is located 65.6 rail kilometers from the terminus of the line at Maeyachi Station.

Matsuiwa Station had one side platform serving a single bi-directional track. The station was unattended.

Matsuiwa Station opened on 11 February 1957. The station was absorbed into the JR East network upon the privatization of the Japan National Railways (JNR) on April 1, 1987. The station was "swept away" save for its platform by the 2011 Tōhoku earthquake and tsunami. Services have now been replaced by a bus rapid transit line.
