This is a list of mammals of Massachusetts. It includes all mammals currently living in Massachusetts, whether resident or as migrants, as well as extirpated species. For the most part, it does not include each mammal's specific habitat, but instead shows the mammal's range in the state and its abundance.

Chiroptera (bats)

In 2008, white nose syndrome was recorded in Massachusetts. Afterwards, the bat population declined by 98%, and thus, in 2012, the little brown myotis, northern long-eared myotis, and tricolored bat were listed as endangered in the state.
