Yamaguchi Danchi Station (山口団地駅, Yamaguchi Danchi-eki) is a railway station on the Sanriku Railway Company’s Rias Line located in the city of Miyako, Iwate Prefecture, Japan.

Yamaguchi Danchi-eki Station is served by the Rias Line, and is located 93.6 rail kilometers from the terminus of the line at Sakari Station.

Yamaguchi Danchi Station opened on 16 October 2010.

During the 11 March 2011 Tōhoku earthquake and tsunami, part of the tracks and the station building at Shimanokoshi were swept away, thus suspending services on a portion of the Sanriku Railway.

However, the portion of the line from Miyako to Tarō resumed operations on 20 March 2011.
