Torii Kiyomitsu (鳥居 清満) was a painter and printmaker of the Torii school of Japanese ukiyo-e art; the son of Torii Kiyonobu II or Torii Kiyomasu II, he was the third head of the school, and was originally called Kamejirō before taking the gō Kiyomitsu. Dividing his work between actor prints and bijinga (pictures of beautiful women), he primarily used the benizuri-e technique prolific at the time, which involved using one or two colors of ink on the woodblocks rather than hand-coloring; full-color prints would be introduced later in Kiyomitsu's career, in 1765.

Though scholars generally note his kabuki prints as lacking originality, they see a grace, beauty, and "dream-like quality" in his prints of young men and women which, at times, rivals that of the work of Suzuki Harunobu, who was just beginning his career at this time. Kiyomitsu continued to produce the billboards and other kabuki-related materials which were the domain of the Torii school, and in those works he was quite traditional and retrospective in his style. However, he was more or less the first Torii artist to experiment outside that field, and to truly emerge into the wider mainstream of ukiyo-e styles, adapting to the use of new techniques and popular subjects. Overall, it is said that the workshop flourished under his direction, but the core "Torii style" was not truly changed or advanced.

Two of his greatest pupils were Torii Kiyotsune, who faithfully continued the Torii traditions, and Torii Kiyonaga, who went on to be a master and innovator in his own right.
