Tadao Oda (Japanese小田 忠雄, Tadao Oda, born 1940 in Kyoto ) is a Japanese mathematician who deals with algebraic geometry.
Oda graduated from Kyoto University with a bachelor's degree in 1962 and a master's degree in 1964. He has a doctorate in 1967 with David Mumford at Harvard University ( Abelian varieties over a perfect field and Dieudonné modules). 1964 to 1968 he was an assistant at the University of Nagoya and 1967/68 Instructor at Harvard. He became an assistant professor at Nagoya University in 1975 and a professor at Tohoku University in 1968. In 2003 he retired.
He was one of the founders of the theory of toric varieties in algebraic geometry in the 1970s and wrote a textbook.
