The white-shouldered fairywren (Malurus alboscapulatus) is a species of bird in the Australasian wren family, Maluridae.

[2] These three species were termed the bicoloured wrens by ornithologist Richard Schodde, and are notable for their lack of head patterns and ear tufts, and their uniform black or blue plumage with contrasting shoulder or wing colour.

[3] Its species name is derived from the Latin words albus "white" and scapulae "shoulder-blades".

[6] The females of M. a. alboscapulatus and M. a. naimii bear a pied plumage, with black upperparts contrasting with white shoulders and underparts.

The preferred habitats of the white-shouldered fairywren are lowland cleared areas; grassland, village gardens, and cane-grass.
