13 Assassins (Japanese: 十三人の刺客, Hepburn: Jūsannin no Shikaku) is a 2010 samurai film directed by Takashi Miike, and starring Kōji Yakusho, Takayuki Yamada, Sōsuke Takaoka, Hiroki Matsukata, Kazuki Namioka and Gorō Inagaki. A remake of Eiichi Kudo's 1963 Japanese period drama film 13 Assassins, it is set in 1844 toward the end of the Edo period in which a group of thirteen assassins—comprising twelve samurai and a hunter—secretly plot to assassinate Lord Matsudaira Naritsugu, the murderous leader of the Akashi clan, to thwart his appointment to the powerful Shogunate Council.

The film marks the third collaboration in which Yamada and Takaoka co-starred, the first two being Crows Zero and Crows Zero 2, both directed by Miike. Principal photography took place over two months, from July to September 2009, in Tsuruoka, Yamagata, in northern Japan. The film opened in Japan on 25 September 2010 and in the United States on 29 April 2011. It received critical acclaim from western critics, who compared it favourably to Akira Kurosawa's oeuvre.
