Carmiol's tanager (Chlorothraupis carmioli) is a species of bird in the cardinal family Cardinalidae that is found in Central America from Nicaragua southwards to northwest Colombia. Its natural habitats are subtropical or tropical moist lowland forests and heavily degraded former forest. It was formerly considered as conspecific with the yellow-lored tanager.

The adult Carmiol's tanager is about 17 cm (6.7 in) long and is an evenly coloured, robust bird. The upper parts are a dull olive green, and the underparts are a rather paler olive green. The throat is slightly yellower than the rest of the underparts, and is streaked in the male while being a uniform pale yellow in the female. The underparts of the female are paler than those of the male, and the female has a yellowish patch in front of the eyes. The beak is relatively stout and is dark-coloured in both sexes. The lemon-spectacled tanager looks similar, apart from its yellow facial markings, but does not share the same range as the olive tanager. Also similar is the ochre-breasted tanager (Chlorothraupis stolzmanni) but again the ranges do not overlap.
