Masai Mara is a large game reserve in south-western Kenya, which is effectively the northern continuation of the Serengeti National Park game reserve in Tanzania.

The Maasai Mara National Reserve (also spelled Masai Mara and known by the locals as 'the Mara') is a large game reserve in south-western Kenya, which is effectively the northern continuation of the Serengeti National Park game reserve in Tanzania. It is named after the Maasai people (the traditional inhabitants of the area) and their description of the area when looked at from afar: "Mara", which is Maa (Maasai language) for "spotted," an apt description for the circles of trees, scrub, savanna, and cloud shadows that mark the area.

It is famous for its exceptional population of Big Cats, game, and the annual migration of zebra, Thomson's gazelle, and wildebeest from the Serengeti every year from July to October, a migration so immense that it is called the Great Migration.

The Maasai Mara National Reserve is only a fraction of the Greater Mara Ecosystem, which includes the following Group Ranches: Koiyaki, Lemek, Ol Chorro Oirowua, Olkinyei, Siana, Maji Moto, Naikara, Ol Derkesi, Kerinkani, Oloirien, and Kimintet.
