Poecilotriccus is a genus of small flycatchers in the family Tyrannidae. Except for the recently described Johnson's tody-flycatcher, all have, at one point or another, been included in the genus Todirostrum. Some species have been known as tody-tyrants instead of tody-flycatchers. Most species are found in South America, but a single species, the slate-headed tody-flycatcher, is also found in Central America. The black-chested tyrant may also belong in this genus, but most place it in the monotypic genus Taeniotriccus.
