Tanzania has the world’s largest population of wild lions.
Tanzania is one of Africa’s most important remaining strongholds for the lion, Panthera leo. Its extensive savannas, abundant prey, and large protected landscapes support major populations across places such as the Serengeti, Ngorongoro, Ruaha, and the Nyerere ecosystem. Recent estimates vary because lions are difficult to count and often move across unfenced borders, but Tanzania consistently ranks first.
The Serengeti–Mara ecosystem is especially famous for its lions and enormous annual movements of wildebeest, zebra, and gazelles. Those migrating herds provide a seasonal food supply that helps sustain predators. Tanzania’s protected-area network also gives lions more room than they have in many other range countries.
A common mistake is to confuse the country with a particular reserve. The Serengeti is one of Tanzania’s best-known lion habitats, but it is not a country. South Africa, Botswana, Kenya, Zambia, and Zimbabwe also hold significant wild lion populations; Tanzania’s distinction is its larger national total.
