The Tsugaru clan (Japanese: 津軽氏, Hepburn: Tsugaru-shi) was a Japanese samurai clan who ruled the northwestern half of what is now Aomori Prefecture in the Tōhoku region of Japan under the Edo period Tokugawa shogunate. The Tsugaru were daimyō of Hirosaki Domain and its semi-subsidiary, Kuroishi Domain. The Tsugaru were in constant conflict with their former overlords, the Nanbu clan of adjoining Morioka Domain. During the Boshin War of 1868-69, the Tsugaru clan fought mostly on the pro-imperial side, although it did briefly join the Ōuetsu Reppan Dōmei. In the Meiji period, the official status of the daimyō was abolished. The former daimyō, including the Tsugaru, became part of the kazoku peerage instead, with Tsugaru Tsuguakira receiving the title of hakushaku (Count).
