Torii Kiyonaga (1752 – June 28, 1815) was a Japanese ukiyo-e printmaker and painter of the Torii school. Originally Sekiguchi Shinsuke, the son of an Edo bookseller, he took on Torii Kiyonaga as an art-name. Although not biologically related to the Torii family, he became head of the group after the death of his adoptive father and teacher Torii Kiyomitsu.
