The crimson-fronted barbet (Psilopogon rubricapillus), also called Sri Lanka barbet, is an Asian barbet endemic to Sri Lanka where it inhabits tropical moist lowland forests up to elevation. The specific epithet combines the Latin ruber meaning "red" with -caillus meaning "-capped" or "-crowned". Gmelin based his description on the "red-crowned barbet" that had been described and illustrated in 1776 by the English illustrator and naturalist Peter Brown. The crimson-fronted barbet is now one of 33 species placed in the genus Psilopogon that was introduced in 1836 by Salomon Müller. The species is monotypic: no subspecies are recognised.
