The freshwater whipray (Urogymnus dalyensis) is a little-known species of stingray in the family Dasyatidae, found in a number of large rivers and associated estuaries in northern Australia. Until recently, this species was regarded as a regional subpopulation of the similar-looking but much larger giant freshwater stingray (U. polylepsis) of Southeast Asia. Typically reaching 1 m (3.3 ft) across, the freshwater whipray has a distinctively shaped, rounded pectoral fin disc, a projecting snout, and a thin tail without fin folds.
