Thalassornis |} Dendrocygnidae is a family of the duck, goose and swan order of birds, Anseriformes.

Most of its members are the 8 species of whistling ducks in the genus Dendrocygna which has a worldwide distribution through the tropics and subtropics. These ducks have, as their name implies, distinctive whistling calls.

The whistling ducks have long legs and necks, and are very gregarious, flying to and from night-time roosts in large flocks. Both sexes have the same plumage, and all have a hunched appearance and black underwings in flight.
