The Serengeti National Park is a large national park in northern Tanzania that stretches over 14,763 km² (5,700 sq mi). It is located in eastern Mara Region and northeastern Simiyu Region and contains over 1.5 million ha (3.7 million acres) of virgin savanna. The park was established in 1940.

The Serengeti is well known for the largest annual animal migration in the world of over 1.5 million blue wildebeest and 250,000 zebra along with smaller herds of Thomson’s gazelle and eland. The national park is also home to the largest lion population in Africa. It is under threat from deforestation, population growth, poaching, and ranching.

The area became a national park in 1940. It was granted strict protection in 1948 when the Serengeti National Park Board of Trustees was formed to administer the national park. The government restricted the movements of the resident Maasai people, and the park boundaries were finalized in 1951.^[6] In 1959, an area of 8,300 km² (3,200 sq mi) was split off in the eastern part of the national park and re-established as Ngorongoro Conservation Area intended to accommodate the traditional land use interests of the Maasai people in a multiple land use area.
