The Higashidōri Nuclear Power Plant (東通原子力発電所, Higashidōri genshiryoku hatsudensho; Higashidōri NPP) is located in the village of Higashidōri in northeastern Aomori Prefecture, on the Shimokita Peninsula, facing the Pacific Ocean. The plant has not generated electricity since Japan's 2011 nationwide nuclear shutdown in the aftermath of the Fukushima Daiichi nuclear disaster.

The plant is unique in Japan in that it is two adjoining sites, one run by one company, the Tōhoku Electric Power Company and the other run by the Tokyo Electric Power Company. The reactors are all of Toshiba design.

Construction of Tohoku Electric's Higashidori Unit 1 began in November 2000 and was completed in December 2005. The design was based on Tohoku Electric's Onagawa Nuclear Power Plant Unit 3, with improvements to the reactor vessel to allow for greater ease in inspection and maintenance. A separate building, apart from the containment structure, is dedicated specifically for the heat exchanger system based on seawater to provide primary coolant for the reactor.
