The black-whiskered vireo (Vireo altiloquus) is a small passerine bird in the family Vireonidae, the vireos, greenlets, and shrike-babblers. It is found in Florida, the Bahamas, many Caribbean islands, and northern and Amazonian South America.
The black-whiskered vireo was originally described in 1808 as Muscicapa altiloqua, mistakenly placing it in the Old World flycatcher family. It was at various times also called Vireosylva altiloqua and Vireo calidris. The black-whiskered vireo has these six subspecies:
