The Panlong River (Chinese: 盘龙江; pinyin: Pánlóng Jiāng) is an urban river in Kunming City, Yunnan, China. It originates at the Songhuaba Reservoir north of Kunming and flows in a north-to-south direction through the city's Panlong, Wuhua and Guandu Districts. It enters the Dian Lake at 24°57′13″N 102°41′11″E / 24.953732°N 102.686274°E.
The river receives a large quantity of municipal sewage and wastewater from industrial effluent.
The Panlong River of Kunming should not be confused with another, longer, river of the same name (also 盘龙江), which flows through south-eastern Yunnan and Vietnam, and enters the Red River.
