The collections of the National Museum of Natural History in Washington, D.C. comprise the majority of the Smithsonian's collections, both in scope and in size, representing over 90% of the Institution's collections.

These collections serve as primary reference materials for exploring and understanding the solid Earth and planet, biological and cultural diversity, evolutionary relationships, biological conservation, and global change. They help us to interpret our biological origins, our cultural heritage, and what the future may hold.
