Bujumbura, formerly Usumbura, is the capital, largest city, and main port of Burundi. It ships most of the country's chief export, coffee, as well as cotton and tin ore. It is on the north-eastern shore of Lake Tanganyika, the second deepest lake in the world after Lake Baikal.

The city center is a colonial town with a large market, the national stadium, a large mosque, and the cathedral for the Archdiocese of Bujumbura. Museums in the city include the Burundi Museum of Life and the Burundi Geological Museum. Other nearby attractions include the Rusizi National Park, the Livingstone-Stanley Monument at Mugere (where David Livingstone and Henry Morton Stanley visited 14 days after their first historic meeting at Ujiji in Tanzania), the presidential palace and the source of the southernmost tributary of the Nile, described locally as the source of the Nile.

Ferries sail from Bujumbura to Kigoma in Tanzania. The city is home to the Bujumbura International Airport and the University of Burundi.
