Madison Grant (November 19, 1865 – May 30, 1937) was an American lawyer, zoologist, anthropologist, and writer known for his work as a conservationist, eugenicist, and as an advocate of scientific racism. Grant is less noted for his far-reaching achievements in conservation than for his pseudoscientific advocacy of Nordicism, a form of racism which views the "Nordic race" as superior.
As a white supremacist eugenicist, Grant was the author of The Passing of the Great Race (1916), one of the most famous racist texts, a book Adolf Hitler referred to as his personal Bible. Grant also played an active role in crafting immigration restriction and anti-miscegenation laws in the United States.
As a conservationist, he is credited with the saving of species including the American bison, helped create the Bronx Zoo, Glacier National Park, and Denali National Park, and co-founded the Save the Redwoods League. Grant developed much of the discipline of wildlife management.
