The hooded dotterel or hooded plover (Thinornis cucullatus) is a species of bird in the family Charadriidae. It is endemic to southern Australia, where it inhabits ocean beaches and subcoastal lagoons. There are two recognised subspecies which form isolated eastern and western populations. The eastern subspecies is of greater conservation concern, with listings varying from Vulnerable in South Australia and Victoria to Critically Endangered in New South Wales.
The hooded dotterel is medium in size for a plover, stocky, and pale in colour. Its length is 19 to 23 cm and its wing-span 23 to 44 cm. It has a black hood and throat with a white collar. Its red bill has a black tip. It has a red eye ring and orange legs. Underparts are white. Males and females are similar. Adults and juveniles are similar except the juveniles do not have the black head and hindneck, which are instead a sandy brown.
