Tokugawa Ienari (Japanese: 徳川 家斉, November 18, 1773 – March 22, 1841) was the eleventh and longest-serving shōgun of the Tokugawa shogunate of Japan who held office from 1787 to 1837. He was a great-grandson of the eighth shōgun Tokugawa Yoshimune through his son Munetada (1721–1764), head of the Hitotsubashi branch of the family, and his grandson Harusada (1751–1827). Ienari died in 1841 and was given the Buddhist name Bunkyouin and buried at Kan'ei-ji.
