Alfred Clarence Redfield (November 15, 1890 – March 17, 1983) was an American oceanographer known for having discovered the Redfield ratio, which describes the ratio between nutrients in plankton and ocean water. In 1966, he received the Eminent Ecologist Award from the Ecological Society of America. His research was used by James Lovelock in the formulation of the Gaia hypothesis, that "Organisms and their environment evolve as a single, self-regulating system." From 1918 to 1924, Redfield worked with Elizabeth M. Bright on studies that involved the effects of radiation and Nereis. In collaboration the team published 12 papers.
