Musō Shinden-ryū (夢想神伝流) is a style of sword-drawing art (iaido) founded by Nakayama Hakudō (中山博道) in 1932. Nakayama Hakudō studied under Hosokawa Yoshimasa, a master of the Shimomura branch (下村派) of Hasegawa Eishin-ryū, and Morimoto Tokumi, a fellow student of Ōe Masaji of the Tanimura branch (谷村派). The name Musō Shinden-ryū most likely comes from the name given to the Shimomura branch by Hosokawa, Musō Shinden Eishin-ryū (無雙神傳英信流).
