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 (7,809 sq mi),making it a candidate for one of the largest national parks in Africa.
The park is situated in central Tanzania between latitude 7 and 8° S and longitude 34 and 35° E about 130 kilometres (81 mi) west of Iringa. The park is a part of the 45,000 square kilometres (17,000 sq mi) Rungwa-Kizigo-Muhesi ecosystem, which includes Rungwa Game Reserve, Kizigo and Muhesi Game Reserves, the Mbomipa Wildlife Management Area, and several other protected areas.
The name of the park is derived from the Great Ruaha River, which flows along its southeastern margin and is the focus for game-viewing. The park can be reached by car on a dirt road from Iringa and there are two airstrips -Msembe airstrip at Msembe (park headquarters), and Jongomeru Airstrip, near the Jongomeru Ranger Post
