The yellow-lored tanager (Chlorothraupis frenata), also known as the olive tanager, is a species of bird in the cardinal family Cardinalidae that is found in South America along the eastern foothills of the Andes from southern Colombia to western Bolivia.

It was formerly considered to be conspecific with Carmiol's tanager of Central America.

The yellow-lored tanager was formally described in 1907 by the German ornithologist Hans von Berlepsch from a specimen collected in the Marcapata District of eastern Peru.

He considered his specimen as a subspecies of Carmiol's tanager and coined the trinomial name Chlorothraupis carmioli frenata.

[9] The yellow-lored tanager sometimes forms small groups of 3-4 individuals.
