What family do all living elephants belong to?

All living elephants belong to the family Elephantidae.

Elephantidae contains the three currently recognized living elephant species: the African bush elephant, the African forest elephant, and the Asian elephant. The African species belong to the genus Loxodonta, while the Asian elephant belongs to Elephas. Together, they are the only surviving members of their family and order.

Elephantidae also includes extinct relatives, most famously mammoths in the genus Mammuthus. Genetic research shows that mammoths are more closely related to Asian elephants than to African elephants, illustrating that Elephantidae includes a deep and branching evolutionary history rather than only modern animals.

The family belongs to Proboscidea, the order containing elephants and their extinct relatives. Mastodons are a common source of confusion: they were proboscideans, but they belonged to a different family, Mammutidae. Hominidae is the family of humans and other great apes, Bovidae includes cattle and antelopes, and Felidae includes cats.
