The Luvua River (or Lowa River) is a river in the Katanga Province of the Democratic Republic of the Congo (DRC). It flows from the northern end of Lake Mweru on the Zambia-Congo border in a northwesterly direction for 350 kilometres (220 mi) to its confluence with the Lualaba River opposite the town of Ankoro. The Lualaba becomes the Congo River below the Boyoma Falls.

Lake Mweru, at an elevation of about 1,000 metres (3,300 ft), is a floodplain lake that has been formed by a process of erosion where the wind has carried off alluvium. The Luvua River leaves the north end of the lake at Pweto in the DRC. The river flows about 350 kilometres (220 mi) northwest to Ankoro, where it meets the Lualaba. The middle course of the river is obstructed by a series of rapids, torrents and cataracts as it drops down from the plateau into the Congo Basin. At Piana Mwanga the falls are used to generate electrictiy for the Manono and Kitotolo mines. The river can be navigated in shallow-draft boats for 160 kilometres (99 mi) of its lower course below Kiambi. The Luvua has its peak discharge between March and May, with significantly lower discharge between September and November.
