The dusky-faced tanager (Mitrospingus cassinii) is a species of bird in the family Mitrospingidae.

The throat is light gray transitioning to olive yellow on the breast and flanks and further to a gray-olive-yellow blend on the belly.

The juvenile is similar but has less yellow on the crown and a buffy tinge to the underparts.

[3] The dusky-faced tanager of subspecies M. c. costaricensis is found along the Caribbean coast from Costa Rica's Heredia Province south to extreme northwestern Panama.

[3] The dusky-face tanager inhabits low dense shrubbery, thickets, and second growth.

Breeding or breeding-condition birds have been recorded between March and May from Costa Rica, Panama, and Colombia.

They chatter all day long with "sputtering notes such as chet or chet-ut" [2].
