The marbled duck, or marbled teal (Marmaronetta angustirostris), is a medium-sized duck. It used to be included among the dabbling ducks, but is now classed as a diving duck. The scientific name, Marmaronetta angustirostris, comes from the Greek marmaros, marbled and netta, a duck, and Latin angustus, narrow or small and rostris billed.

This duck formerly bred in large numbers in the Mediterranean region, but is now restricted to a few sites in southern Spain, northwest Africa and in Israel. In the east it survives in the Mesopotamian marshland in southern Iraq and in Iran (Shadegan Marshes - the world's most important site), as well as isolated pockets in Turkey, Armenia, Azerbaijan, Iraq and further to the east in western India and western China. Its breeding habitat is lowland where they lay their eggs in long grass or in high trees. They may lay 7 to 10 cream eggs. They are common in private collections but are a nervous and flighty bird. In some areas birds disperse from the breeding grounds, and have been encountered in the winter period in the Sahel zone, south of the Sahara.

These are gregarious birds, at times even when nesting. Outside the breeding season flocks are often small, although large wintering flocks have been reported in some areas. The largest winter concentration known is in Khuzestan, Iran.

In 2011, a group of Iraqi ornithologists counted a single flock of the rare marbled teal on the lakes of the Iraqi marshes, numbering at least 40,000 birds.
