The Chaco puffbird or streak-bellied puffbird, is a species of bird in the family Bucconidae, the puffbirds. It is found in eastern Bolivia to south-central Brazil, south through western Paraguay to central Argentina. It is found in various open to semi-open habitats, ranging from to semi-humid woodland along the lower Amazon River. It is generally fairly common.
