Mutsu Province (陸奥国, Mutsu no Kuni; Japanese pronunciation: [mɯꜜ.tsɯ (no kɯ.ɲi)]), officially called Rikuō Province (陸奥国, Rikuō no kuni) was an old province of Japan in the area of Iwate and Aomori prefecture.

It was also known as Ōshū (奥州) or Rikushū (陸州). In the Meiji era, the province was cut down to cover only present-day Aomori and given the new name Rikuō Province, which retained the original kanji.
