Edward Murray East (October 4, 1879 – November 9, 1938) was an American plant geneticist, botanist, agronomist and eugenicist. He is known for his experiments that led to the development of hybrid corn and his support of 'forced' elimination of the 'unfit' based on eugenic findings. He worked at the Bussey Institute of Harvard University where he performed a key experiment showing the outcome of crosses between lines that differ in a quantitative trait.
