The Yellow-crested Manakin (Heterocercus flavivertex), also called Yellow-crowned Manakin, is a species of bird in the Pipridae family, the Manakins. It is found in the Amazon Basin of Brazil and Colombia; also the Orinoco River and southern Venezuela. Its natural habitats are subtropical or tropical moist lowland forests and subtropical or tropical dry shrubland.

Amazon's Rio Negro range

The Yellow-crested Manakin's range is in a section of the northwestern Amazon Basin, (Amazonas state), and mostly the Rio Negro drainage and the adjacent northwest headwaters to the Caribbean-flowing Orinoco River of Venezuela. Its southern range limit is mostly the Rio Negro southern side, to its Amazonian headwaters in eastern Colombia.

Downriver it is found on the final 200km of the south flowing Branco River of Roraima state; its contiguous section of range extends eastward, only north of and abutting the Amazon River to Amapá state's Trombetas River, the final third. It is not found downriver eastwards beyond the Trombetas"?Amazon River confluence.
