Tadashi Nakayama or Tadasi Nakayama (中山 正, Nakayama Tadashi, July 26, 1912, Tokyo Prefecture – June 5, 1964, Nagoya) was a mathematician who made important contributions to representation theory.

He received his degrees from Tokyo University and Osaka University and held permanent positions at Osaka University and Nagoya University. He had visiting positions at Princeton University, Illinois University, and Hamburg University. Nakayama's lemma, Nakayama algebras, Nakayama's conjecture and Murnaghan–Nakayama rule are named after him.
