The Chesterfield Island stingaree or Deforge's stingaree (Urolophus deforgesi) is a little-known species of stingray in the family Urolophidae, endemic to the continental slope off the Chesterfield Islands. Reaching 34 cm (13 in) long, it has a rounded, diamond-shaped pectoral fin disc colored plain brown above and pale below, with a short head. There is a narrow, skirt-shaped curtain of skin between its nostrils. Its tail is relatively long and terminates in a leaf-shaped caudal fin; there are no dorsal fin or lateral skin folds. This species has been listed under Least Concern by the International Union for Conservation of Nature (IUCN), as there is little fishing activity within its range.
