The round fantail stingray (Taeniurops grabatus) or round stingray, is a poorly known species of stingray in the family Dasyatidae. It inhabits sandy, muddy, or rocky coastal habitats in the eastern Atlantic Ocean and the southern Mediterranean Sea. This dark-colored ray typically reaches a width of 1 m (3.3 ft), and can be identified by its nearly circular pectoral fin disk, short tail, and mostly bare skin. The round fantail stingray hunts for fishes and crustaceans on the sea floor, and exhibits an aplacental viviparous mode of reproduction. The International Union for Conservation of Nature (IUCN) has assessed the conservation status of this species as Near Threatened.
French naturalist Étienne Geoffroy Saint-Hilaire originally described the round fantail stingray in 1817 as Trygon grabatus, from the Latin grabatus meaning "bed". His account was published in the first volume of the folio Poissons du Nil, de la mer Rouge et de la Méditerranée. Subsequent authors moved this species to the genus Taeniura. No type specimens are known.
