Imagawa Norinobu (今川 範叙, 1829 – November 3, 1887) was a Japanese samurai of the late Edo period.
Norinobu was influential in the last days of the Tokugawa shogunate, being appointed a wakadoshiyori shortly before its demise and working for the new government to show clemency to the Tokugawa family.
Born the 3rd son of Imagawa Yoshiyori, he was a hatamoto who headed one of the 26 families holding the position of kōke (master of ceremonies) in the Tokugawa shogunate,[1] a position whose most famous holder was Kira Yoshinaka of Chushingura fame.
He was a direct descendant of the famed Imagawa Yoshimoto and his son Ujizane.
Living the rest of his life in quiet obscurity, Norinobu died in 1887.
