The White-throated Oxylabes (Oxylabes madagascariensis) is a species of passerine once thought to be a species of Old World warbler in the Sylviidae family. It is found only in Madagascar. Recent research indicates it is part of an endemic Malagasy radiation currently known as the Malagasy warblers (Cibois et al. 2001).

Its natural habitat is subtropical or tropical moist lowland forests.
