The olive-green tanager (Orthogonys chloricterus) is a species of bird in the family Mitrospingidae.

[6] The olive-green tanager is found only in southeastern Brazil, from Espírito Santo state south to eastern Santa Catarina and northeastern Rio Grande do Sul.

It feeds in the mid- to upper levels of the forest, usually picking prey from leaves, and it also sallies for flying insects.

[6] One olive-green tanager was noted carrying nest material to a bromeliad in a large tree.

[1] "Despite local population declines and fragmentation, its long-term viability should be assured if protection continues for the parks and reserves where it remains.
