André Frédéric Cournand (September 24, 1895 – February 19, 1988) was a French physician and physiologist.
He was awarded the Nobel Prize in Physiology or Medicine in 1956 along with Werner Forssmann and Dickinson W. Richards for the development of cardiac catheterization.
Born in Paris, Cournand emigrated to the United States in 1930 and, in 1941, became a naturalized citizen. For most of his career, Cournand was a professor at the Columbia University College of Physicians and Surgeons and worked at Bellevue Hospital in New York City.
