Nyamagabe is a district (akarere) in Southern Province, Rwanda. Its capital is Gasaka.
The district lies between Butare and Cyangugu in the south-west of Rwanda, and contains much of the former Gikongoro Province, which was disbanded in 2006. It also contains the eastern half of Nyungwe Forest, a popular tourist destination, being one of the last remaining forest areas of Rwanda and home to chimpanzees and many other species of primate.
Nyamagabe district is divided into 17 sectors (imirenge): Buruhukiro, Cyanika, Gatare, Kaduha, Kamegeli, Kibirizi, Kibumbwe, Kitabi, Mbazi, Mugano, Musange, Musebeya, Mushubi, Nkomane, Gasaka, Tare and Uwinkingi.
The Kigeme refugee camp is located in the district. A Turi Kumwe Centre, housing "a Police post as well as migration and camp management offices" was opened in the camp in 2014.[2]
