Kōriyama Castle (郡山城) was a castle in Shiwa, Iwate Prefecture, Japan. It was built in 1335 on a terrace overlooking Kitakami River for Shiba Ienaga, the son of Shiba Takatsune. Later occupants include Nakano Yasuzane after Nanbu Nobunao defeated the Shiba clan.
It has had multiple names over the years, including its original name, Kōsuiji Castle (高水寺城), as well as the Shiwa Imperial Palace or Shiba Imperial Palace (斯波御所, Shiwa Gojo or Shiba Gojo). The castle ruins are now within Shiroyama City Park in Shiwa. Only a number of dry moat sections and a few earthworks remain.
