The cinnamon-breasted tody-tyrant (Hemitriccus cinnamomeipectus) is a species of bird in the family Tyrannidae, the tyrant flycatchers.

[4][5][6] The cinnamon-breasted tody-tyrant's overall range spans only about 300 km (190 mi) north to south but it is not found continuously within it.

The species primarily inhabits the understory of stunted humid montane forest on nutrient-poor soils.

It typically forages singly or in pairs and occasionally joins mixed-species feeding flocks.

It mostly takes prey using short upward sallies from a perch to grab it from the underside of leaves.

The cinnamon-breasted tody-tyrant's song is "a tinkling, descending, rapid trill: tEEEeeeerrrrr" and its call "a series of rising, mewed weeb notes".
