Sannohe Castle (三戸城, Sannohe-jō) was a Muromachi period Japanese castle located in the center of what is now the town of Sannohe, in Sannohe District of Aomori Prefecture, in the Tōhoku region of far northern Japan. It was located on a river terrace of the Mabechi River, which formed part of its natural defenses. The castle site was designated a National Historic Site of Japan in March 2022.
