Ernest Brown Babcock (July 10, 1877 – December 8, 1954) was a United Statesplantgeneticist who pioneered the understanding of plant evolution in terms of genetics. He is particularly known for seeking to understand by field investigations and extensive experiments, the entire polyploidapomictic genus Crepis, in which he recognize 196 species. In his career, he published more than 100 articles and books explaining plant genetics, including the seminal textbook (with Roy Elwood Clausen) Genetics in relation to agriculture.
