Suzuki Kiitsu (Japanese: 鈴木其一, 1796 – 1858) was a Japanese painter of the Rinpa school.
A student of the famous painter Sakai Hoitsu (1761–1828), he was for a long time considered a minor member of Rinpa school of Japanese painting. In recent years his work has been reevaluated and gained recognition, leading to a series of major exhibitions of his art in 2016-2017 in Tokyo, Hyogo and Kyoto.
Kiitsu is best known for his byōbu folding screens, often a reinterpretation of screens by other Rinpa artists, such as his massive Wind God and Thunder God following Tawaraya Sōtatsu (c. 1570 – c. 1640), Ogata Kōrin (1658–1716) and Hoitsu. But he has been most acclaimed for his original screens, including his famed Morning Glories and Mountain Stream in Summer and Autumn.
He was also a notable master with many pupils. Although he was not the official successor of Hoitsu's school, he trained himself many of the Edo Rinpa artists. This has sometimes been labeled as the Kiitsu school of Edo Rinpa.
