The Koga Domain (古河藩 Koga-han?) was a Japanese domain of the Edo period, located in Shimōsa Province (present-day Koga, Ibaraki). The first lord of Koga was Ogasawara Hidemasa, who was granted it as a fief following Tokugawa Ieyasu's move to the Kantō region.

In the han system, Koga was a political and economic abstraction based on periodic cadastral surveys and projected agricultural yields.[1] In other words, the domain was defined in terms of kokudaka, not land area.[2] This was different than the feudalism of the West.
