Tsugaru Tamenobu (津軽 為信, January 18, 1550 – March 29, 1608) was a Japanese daimyo of the late Sengoku through early Edo period. He was known as Ōura Tamenobu earlier on in his life. Tamenobu had at one time battled against Nanbu Nobunao. Following this, Tamenobu submitted to Toyotomi Hideyoshi and fought against the Hōjō during the siege of Odawara. It was at this time that Tamenobu took the name of Tsugaru. Tamenobu followed in capturing Namioka Castle during the year 1590. During the Azuchi-Momoyama period of the 17th century, Tamenobu supported the Tokugawa following the Sekigahara Campaign of 1600, at which point his revenues increased to 47,000 koku. Despite his support to Tokugawa, Tamenbou maintained good relationship with Ishida Mitsunari, who was a personal friend of his. After the western forces' certain defeat, he sent escorts to protect Ishida Mitsunari's family from harm and married Ishida's daughter to his heir.
