Naka-Oguni Station (中小国駅, Naka-Oguni-eki) is a railway station on the Tsugaru Line in the town of Sotogahama, Aomori, Japan, operated by East Japan Railway Company (JR East).

[1] Naka-Oguni Station has one side platform serving a single bidirectional track.

With the privatization of JNR on April 1, 1987, it came under the operational control of JR East.

With the opening of the Tsugaru Kaikyō Line on March 13, 1988, operation of the station was shared between JR East and JR Hokkaido, and the station was regarded as the southern starting point of the Tsugaru Kaikyō Line for the determination of railway fares, although no trains of Kaikyō Line stopped at the station, and the effective southern terminus for all Tsugaru Kaikyō Line trains was at Aomori Station.

The junction also marks the border between the electrified portion of the Tsugaru Line (Aomori to Naka-Oguni) and the non-electrified portion (Naka-Oguni to Minmaya), as well as the border between JR East and JR Hokkaido.
