The white-winged widowbird (Euplectes albonotatus) is a species of passerine bird in the family Ploceidae native to Africa south of the Sahara.

[2] It is highly sexually dimorphic in its breeding season, during which the male's yellow plumage turns dark and he gains more white feathers, contrasting with the female's predominantly pale coloration.

[3] A proposal has been made for race sassii, which is found along the northwestern shore of Lake Tanganyika.

The breeding male is distinguished from the yellow-mantled widowbird by its shorter tail, wing color, lack of yellow on its back, and paler bill.

Oval nests, built solely by the male,[7] are located in the branches of trees or shrubs.
