The olive-backed oriole (Oriolus sagittatus), or white-bellied oriole, is a very common medium-sized passerine bird native to northern and eastern Australia and south-central New Guinea.

The most wide-ranging of the Australasian orioles, it is noisy and conspicuous.

The olive-backed oriole was originally described in the genus Coracias by the English ornithologist John Latham in 1801.

Females have cinnamon-edged wings and both sexes have reddish bills and eyes.

Where the green oriole specialises in damp, thickly vegetated habitats in the tropical far north, the olive-backed oriole is more versatile, preferring more open woodland environments, and tolerating drier climates (but not desert).
