Kikuo Chishima (千島 喜久男, Chishima Kikuo; October 10, 1899 – October 23, 1978) was a Japanese medical researcher known for advocating a variant of the Soviet medical biologist Olga Lepeshinskaya's pseudoscientific cellular theories. His work in this field, referred to as neo-haematology, has been largely discredited.
