The lemon-spectacled tanager (Chlorothraupis olivacea) is a species of bird in the family Cardinalidae.

It is very similar in appearance to the olive tanager but the male is a rather darker shade of dull olive-green with the underparts have less yellow on the throat.

[2] The three species do not share common ranges; the lemon-spectacled tanager is native to western Colombia and northwestern Ecuador, the ochre-breasted tanager occurs at higher elevations, and the olive tanager occurs further south in the eastern foothills of the Andes in southern Colombia, Peru and Bolivia, with a disjunct population in Central America.

It is a noisy species with a loud call, often a rapidly repeated "treu-treu-treu-treu".

Its population has not been quantified and may be declining slightly, but the bird has a very wide range and does not meet the criteria for being listed in a more-threatened category.
