National Bison Day

National Bison Day is observed every year on the first Saturday of November. The day honors the American bison, an animal deeply connected with the history, ecology, and cultural heritage of North America. Bison appear in the wild, in national parks, on coins, in sports logos, and in official symbols, making them one of the most recognizable animals in the United States.

History of National Bison Day

Bison have long held great importance for many Indigenous peoples, serving as a source of food, clothing, tools, shelter, and spiritual meaning. For centuries, vast herds roamed across North America and played an essential role in the grassland ecosystem.

By the late 19th and early 20th centuries, overhunting, habitat loss, and westward expansion had brought bison close to extinction. Only a small number survived in protected areas and private herds. Conservation efforts later helped restore bison populations, though their numbers remain far below the massive herds that once existed.

National Bison Day gained official recognition through U.S. Senate resolutions beginning in 2012. In 2016, the American bison was designated the national mammal of the United States, recognizing its historic, ecological, and cultural importance.
