The little brown bat (sometimes called little brown myotis) (Myotis lucifugus) is a species of the genus Myotis (mouse-eared bats), one of the most common bats of North America. The little brown bat has been a model organism for studying bats.

Little brown bats are now at a higher threat due to white nose syndrome in eastern North America. Many states have made special considerations with respect to the disease, including listing them as a sensitive or protected species.

Canada has listed them as an endangered species. It is estimated that 94% of the population in the eastern half of the country has died over the last few years from WNS, and the disease is moving westward at a rate that may see them extirpated within as little as 12 years.
