George Harrison Shull (1874 to 1954) was an American plant geneticist who played a central role in developing hybrid maize and in establishing the genetic basis of heterosis, the increased vigor often seen in hybrid offspring. Science ran in his family: several of his siblings became scientists in related fields, and his niece Elizabeth Shull Russell was a geneticist elected to the National Academy of Sciences.

George Harrison Shull (April 15, 1874, September 28, 1954) was an American plant geneticist who played a central role in the development of hybrid maize and in establishing the genetic basis of heterosis. He was one of several siblings who pursued careers in biology; his brothers included the plant physiologist Charles Albert Shull, professor at the University of Chicago and founding editor-in-chief of Plant Physiology; the zoologist Aaron Franklin Shull of the University of Michigan; and the botanist and botanical illustrator J. Marion Shull.
