The Golden-crowned Manakin (Lepidothrix vilasboasi) is a small species of perching bird in the manakin family (Pipridae). It is endemic to the south-central Amazon Rainforest in Brazil, and it is threatened by habitat loss. Helmut Sick described this species in 1959 based on a series of specimens collected a few years before, but it was only rediscovered (in part due to confusion over the original type locality) in 2002. Except for the yellow crown of the male, it closely resembles the Opal-crowned Manakin and Snow-capped Manakin, but their distributions are not known to overlap.
