The Guianan greenlet (Tunchiornis luteifrons), also known as the olive-crowned greenlet, is a passerine bird in the family Vireonidae, the vireos. It is found in South America in the Guiana Shield region which includes the countries and territories of Guyana, Suriname, French Guiana, as well as sections of northern Brazil and eastern Venezuela. It was split from the ochre-crowned greenlet in 2025 by AviList and the Clements Checklist. Owing to its recent separation as a species, virtually nothing distinctive is known about its natural history.
