The ] (''Loxodonta africana''), of the order ], is the largest living land animal.

The following is a list of the heaviest living animals, which are all ]s. These whales also qualify as the largest living mammals. Since no scale can accommodate the body of a large whale, most whales have been weighed by parts.
