The  Maasai Mara National Reserve (also known as Masai Mara and by the locals as The Mara) is a large game reserve in Narok County,Kenya, contiguous with the Serengeti National Park in Mara Region, Tanzania. It is named in honor of the Maasai people (the ancestral 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 globally famous for its exceptional population of lions, leopards and cheetahs, and the annual migration of zebra, Thomson's gazelle, andwildebeest to and from the Serengeti every year from July to October, known as the Great Migration.
