Panthera leo melanochaita is a lion subspecies in Southern and East Africa. In this part of Africa, lion populations are regionally extinct in Lesotho, Djibouti and Eritrea, and are threatened by loss of habitat and prey base, killing by local people in retaliation for loss of livestock, and in several countries also by trophy hunting. Since the turn of the 21st century, lion populations in intensively managed protected areas in Botswana, Namibia, South Africa and Zimbabwe have increased, but declined in East African range countries. In 2005, a Lion Conservation Strategy was developed for East and Southern Africa.

The lion is a large cat of the genus Panthera, native to Africa and India. It has a muscular, broad-chested body; a short, rounded head; round ears; and a hairy tuft at the end of its tail. It is sexually dimorphic; adult male lions are larger than females and have a prominent mane. It is a social species, forming groups called prides. A lion's pride consists of a few adult males, related females, and cubs. Groups of female lions usually hunt together, preying mostly on large ungulates. The lion is an apex and keystone predator; although some lions scavenge when opportunities occur and have been known to hunt humans, lions typically do not actively seek out and prey on humans.
