Ojiya Station (小千谷駅, Ojiya-eki) is a railway station on the Jōetsu Line in the city of Ojiya, Niigata, Japan, operated by the East Japan Railway Company (JR East).

Ojiya Station is served by the Jōetsu Line, and is located 149.4 kilometers from the starting point of the line at Takasaki.

The station has one ground-level side platform and one island platform connected by a footbridge; however, one side of the island platform is not in use. The station has a Midori no Madoguchi staffed ticket office.

The station opened on 1 November 1920, originally named Higashi-Ojiya Station (東小千谷駅; lit. "East Ojiya Station") to distinguish it from the existing Ojiya Station on the Uonuma Railway. It was renamed simply Ojiya Station on 1 August 1932 after the Uonuma Railway station was renamed Nishi-Ojiya Station (西小千谷駅; lit. "West Ojiya Station") in July 1932. With the privatization of Japanese National Railways (JNR) on 1 April 1987, the station came under the control of JR East.

In fiscal 2017, the station was used by an average of 1282 passengers daily (boarding passengers only).
