Camptostoma is a small genus of tyrant flycatchers. It contains two species.
- Northern beardless tyrannulet, Camptostoma imberbe
- Southern beardless tyrannulet, Camptostoma obsoletum
These are very small passerine birds which breed in the tropical and subtropical Americas from the southernmost USA south to Paraguay, Bolivia, and Argentina. The two species are similar, and were once considered conspecific. However, they overlap without interbreeding in central Costa Rica.
These are species of in light forests, cultivation and gardens with trees. The domed nest is made of plant fibre or leaves with a side entrance.
