Tōdō Heisuke (藤堂 平助, 1844 – December 13, 1867) was a samurai of Japan's late Edo period who served as the eighth unit captain of the Shinsengumi.
Although he was said to be an illegitimate child of Tōdō Takayuki, the 11th generation lord of the Tsu domain, this is highly debatable.
Sources vary as to his role in the Serizawa Kamo (one of the original commanders of the Shinsengumi) assassination.
Tōdō, having joined Itō Kashitarō's breakaway Goryō Eji (御陵衛士) group, left the Shinsengumi.
According to Nagakura Shinpachi's Shinsengumi Tenmatsuki, Kondō had wished to spare Tōdō's life.
