The buff-breasted flycatcher (Empidonax fulvifrons) is a small insectivorous bird.

It is the smallest Empidonax flycatcher, typically ranging from 11.5 to 13 cm (4.5 to 5 in) in size.

Adults have olive gray upper bodies, darker coloration on the wings and tail, conspicuous white eye rings, white wing bars, small bills, and short tails.

The range of the buff-breasted flycatcher extends from extreme southeastern Arizona in the United States through Mexico to southern Honduras.

To feed, they often wait on an open perch of a shrub or low branch of a tree and fly out to catch insects in flight.
