Mutsu Province (陸奥国, Mutsu no kuni), also known as Michinoku,was an old province of Japan in the area of Fukushima, Miyagi, Iwate and Aomori Prefectures on the island of Honshū. It was also known as Ōshū (奥州) or Rikushū (陸州).

The boundaries of Mutsu were formally established during the reigns of Empress Genshō and Empress Kōken.
In the Meiji period, the provinces of Japan were converted into prefectures. Maps of Japan and Mutsu Province were reformed in the 1870s.
Tsutsukowake jinja and Shiogama jinja were the chief Shinto shrines (ichinomiya) of Mutsu.
