Carl Ferdinand Cori, ForMemRS (December 5, 1896 – October 20, 1984) was an Austrian-American biochemist and pharmacologist born in Prague (then in Austria-Hungary, now Czech Republic) who, together with his wife Gerty Cori and Argentine physiologist Bernardo Houssay, received a Nobel Prize in 1947 for their discovery of how the glucose derivative glycogen (animal starch) is broken down and resynthesized in the body for use as a store and source of energy. In 2004, both Coris were designated a National Historic Chemical Landmark in recognition of their work that elucidated carbohydrate metabolism.
