Fiji's landscape is carved by numerous rivers and streams that drain its volcanic islands, supply freshwater, and shape coastal ecosystems. This article presents an organized list of notable rivers by island, with representative tributaries and brief notes on their roles in transport, agriculture, ecology and culture. For general context on waterways see rivers and for geographic background refer to Fiji.

Rivers by island (representative)

  • Viti Levu (largest island) — major rivers include the Rewa River (the longest and most significant drainage system), with well-known tributaries such as Wainibuka and Wainimala; the Sigatoka River; the Navua River; the Nadi River; and the Ba River.
  • Vanua Levu — principal waterways include the Dreketi River and the Labasa River, which drain large central basins and support local agriculture.
  • Taveuni and smaller islands — Taveuni and many outer islands have numerous short, steep streams that flow rapidly to the coast; these are important for local water supply and biodiversity.
  • Kadavu and Lau islands — islands of lower relief with short coastal rivers and many freshwater streams that feed mangrove and reef systems.

Characteristics and uses

Fijian rivers tend to be short to moderate in length, with rapid flows on steep terrain and broader floodplains where they reach lowlands. They provide irrigation for sugarcane and other crops, freshwater for communities, sites for recreational rafting or fishing, and occasional potential for small-scale hydropower. Rivers also transport sediment to coastal reefs and form estuaries and mangroves that support fisheries.

History, ecology and management

These waterways have cultural importance to indigenous communities and were historically used for canoe travel and resource gathering. Modern challenges include deforestation in headwaters, watershed erosion, flood risk in rainy seasons, and the need for integrated management to protect water quality and downstream marine ecosystems.

Organization and further reading

Rivers are commonly listed by island in clockwise order starting at an island's north end; tributaries are normally shown beneath their parent stream (tributaries). Detailed, island-by-island inventories include many smaller streams not named here. For comprehensive maps and technical data consult regional hydrological surveys and local resources.
