The Xingu River ray, white-blotched river stingray, or polka-dot stingray (Potamotrygon leopoldi) is a species of freshwater fish in the Potamotrygonidae family. It is endemic to the Xingu River basin in Brazil and prefers rocky bottoms.[1] It is sometimes kept in aquaria.[1]

P. leopoldi reaches up to 40 cm (16 in) in disc width,[2] 75 cm (30 in) in total length and 20 kg (44 lb) in weight.[3] Females grow larger than males.[4] It is closely related to the similar P. henlei from the Tocantins River basin and P. albimaculata from the Tapajós River basin.[5]
