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.

Carmiol's tanager was formally described in 1868 by the American ornithologist George Newbold Lawrence from a specimen collected in Costa Rica.

[2][3] Carmiol's tanager is now one of four species placed in the genus Chlorothraupis that was introduced in 1863 by Osbert Salvin and Frederick DuCane Godman.

[4] The common name and the specific epithet commemorate Franz Carmiol, the son of a German immigrant to Nicaragua, who had collected the specimen for the Smithsonian Institution.
