Tsuchizawa Station (土沢駅, Tsuchizawa-eki) is a railway station in the city of Hanamaki, Iwate, Japan, operated by East Japan Railway Company (JR East).

Tsuchizawa Station is served by the Kamaishi Line, and is located 15.9 rail kilometers from the terminus of the line at Hanamaki Station.

The station has two opposed ground-level side platforms connected to the station building by a level crossing.

Tsuchizawa Station opened on 24 October 1913 as a station on the Iwate Light Railway (岩手軽便鉄道), a 762 mm (2 ft 6 in) light railway extending 65.4 km from Hanamaki to the now-defunct Sennintōge Station (仙人峠駅).

The station was absorbed into the JR East network upon the privatization of the Japanese National Railways (JNR) on 1 April 1987.
