Sanjuro (Japanese: 椿三十郎, Hepburn: Tsubaki Sanjūrō) is a 1962 Japanese jidaigeki film directed, co-written and edited by Akira Kurosawa, starring Toshiro Mifune. It is a sequel to Kurosawa's 1961 Yojimbo.

Originally an adaptation of the Shūgorō Yamamoto novel Hibi Heian, the script was altered following the success of the previous year's Yojimbo to incorporate the lead character of that film.
