Ruaha National Park is the largest national park in Tanzania. The addition of the Usangu Game Reserve and other important wetlands to the park in 2008 increased its size to about 20,226 square kilometres, making it the largest park in Tanzania and East Africa.

It is located in the middle of Tanzania about 130 kilometres from Iringa. The park is part of a more extensive ecosystem, which includes Rungwa Game Reserve, Usangu Game Reserve, and several other protected areas.
The name of the park is derived from the Great Ruaha River, which flows along its South-Eastern margin and is the focus for game-viewing. The park can be reached by car via Iringa and there is an airstrip at Msembe, park headquarters.
