Hitachi Province (常陸国, Hitachi no Kuni; Japanese pronunciation: [çi̥ꜜ.ta.tɕi (no kɯ.ɲi), çi̥.taꜜ.tɕi-]) was an old province of Japan in the area of Ibaraki Prefecture. It was sometimes called Jōshū (常州). Hitachi Province bordered on Shimōsa (Lower Fusa), Shimotsuke, and Mutsu (Iwase -1718-, Iwashiro -1869-, Iwaki -1718- and -1869-) Provinces. Generally, its northern border was with Mutsu.

It was part of Mutsu Province; the area once was part of Iwase Province created during the reign of Empress Genshō. The Yōrō Ritsuryo established the Iwase Province in 718 through the division of the Michinoku Province (Mutsu Province). It was composed of five districts of Shirakawa (白河), Iwase (石背), Aizu (会津), Asaka (安積) and Shinobu (信夫). The area encompassed by the province reverted to Mutsu some time between 722 and 724.
