The Choco tyrannulet (Zimmerius albigularis) is a species of bird in the family Tyrannidae, the tyrant flycatchers. It is found in forests in the Chocó of south-western Colombia and western Ecuador. Until recently, it was considered a subspecies of the golden-faced tyrannulet. Following the split, it has not been rated by BirdLife International, but despite being restricted to a region with extensive habitat destruction, it is generally fairly common, and therefore unlikely to be seriously threatened.
