Shinsui Itō (Japanese: 伊東 深水; 4 February 1898 – 8 May 1972), was the pseudonym of a Nihonga painter and ukiyo-e woodblock print artist in Taishō and Shōwa period Japan. He was one of the great names of the shin-hanga art movement, which revitalized the traditional art after it began to decline with the advent of photography in the early 20th century. His real name was Hajime Itō (Japanese: 伊東 一).
