Mizuno Nobumoto (水野 信元, 1537-January 27, 1576) was a Japanese daimyō of the Sengoku period.
He was Tokugawa Ieyasu's uncle through Matsudaira Hirotada's marriage to his sister, Odai no Kata.
[1] In 1542, Nobumoto sided with Oda Nobuhide, but later served to Tokugawa Ieyasu.
Later, Nobunaga marched his army north and attacked the Imagawa forces in the Battle of Muraki Castle.
His brother, Mizuno Tadashige succeeded him and helped Tokugawa Ieyasu during the Battle of Sekigahara in 1600 before getting killed by Kaganoi Shigemochi, ending the family line.
