Kiiti Morita (森田 紀一 Morita Kiichi, February 11, 1915, Hamamatsu – August 4, 1995, Tokyo) was a Japanese mathematician working in algebra and topology.
He received his Ph.D. from the University of Osaka in 1950 and was professor at the University of Tsukuba.
He introduced the concepts now known as Morita equivalence and Morita duality which were given wide circulation in the 1960s by Hyman Bass in a series of lectures. The Morita conjectures on normal topological spaces are also named after him.
