A state mammal is the official mammal of a U.S. state as designated by a state's legislature. The first column of the table is for those denoted as the state mammal, and the second shows the state marine mammals. Animals with more specific designations are also listed. Many states also have separately officially designated state birds, state fish, state butterflies, state reptiles, and other animals. Listed separately are state dogs and state horses.
Key: Years in parentheses denote the year of adoption by the state's legislature.
