Nagaoka Station (長岡駅, Nagaoka-eki) is a railway station in the city of Nagaoka, Niigata, Japan, operated by East Japan Railway Company (JR East). The station is located 270.6 kilometers from Tokyo.

Nagaoka Station is served by the following lines:

• Joetsu Shinkansen
• Shinetsu Main Line
• Joetsu Line

The station has two ground-level island platforms for normal trains. However, Track 1 is not used by any regularly-scheduled trains and it is normally closed off to passengers.

There are two elevated opposed side platforms for the Joetsu Shinkansen, with two through tracks in the middle. The Shinkansen platforms, constructed under the tenets of the 1973 Basic Plan to build out the high-speed network, were designed to be converted to island platforms to interface with the Uetsu Shinkansen, which was planned to run alongside the Joetsu Shinkansen between Nagaoka and Niigata. The opposite side of Track 11's platform is fenced, with a trackless railbed reserved for this purpose, and there is space reserved outside the station structure to allow the construction of a railbed for a track adjoining the platform for Track 12. As of 2016, however, there are no plans to revisit the "Uetsu Shinkansen".

The station building is located above the local platforms and underneath the Shinkansen platforms. The station has a Midori no Madoguchi staffed ticket office.
