Kirungu is a town located in the Democratic Republic of the Congo in Tanganyika province. It is inland from Moba port, the administrative center of Moba Territory.

Kirungu was formerly called Baudouinville (or Boudewijnstad in Dutch), and was the site of a White Fathers mission founded in 1893 by Father Victor Roelens. The Roman Catholic Diocese of Kalemie–Kirungu is based in Kirunga and Kalemie, 140 kilometres (87 mi) to the north.

Kirungu is situated a few kilometers from the western shore of the southern part of Lake Tanganyika, 140 kilometres (87 mi) south-east of Kalemie, to which it is linked by regular boat services. It is on a plateau 400 metres (1,300 ft) above the lake and 5 km from Moba. The town lies along National Highway 34 which connects it to the jetty in Moba and to the north-south running National Highway 5 in the west.

Kirungu lies just south of the Mulobozi river. The Marungu highlands, a range of steep rugged hills, rises behind the town, bisected by the Mulobozi. The smaller northern section rises to an elevation of about 2,100 metres (6,900 ft), and the larger southern section to about 2,460 metres (8,070 ft).

The town contains the Stade du Kirungu, the Radio Communautaire de Moba headquarters and the Hopital de Reference Kirungu.
