The chestnut-bellied thrush (Turdus fulviventris) is a species of bird in the family Turdidae. It is found in Colombia, Ecuador, Peru, and Venezuela. Its natural habitats are subtropical or tropical moist montane forests and heavily degraded former forest.

The chestnut-bellied thrush grows to a length of about 25 cm (10 in). The adult male has a black head, a black throat with some white streaking, a dark grey back and dusky wings and tail. The upper breast is pale grey and the lower breast and belly are rufous. The beak is yellow, the narrow eye ring is orange and the legs are dull yellow. The female is similar in appearance but rather duller. It is the only thrush in the genus Turdus with a rufous belly to be found in the northern Andes. The song is not often uttered, but consists of a series of disjointed phrases with some buzzes and short trills in between.
