The Museum of Southwestern Biology is a research and teaching facility in the Department of Biology of the University of New Mexico. The museum's collections include vascular plants, invertebrates and vertebrates from the American West, Central and South America, and from throughout the world. It is open to visitors by appointment.
The museum is thought to hold the largest collection of frozen tissue samples in the western hemisphere and has assisted in the study of emerging zoonotic pathogens such as the orthohantavirus and the Lassa mammarenavirus.
