Blyth's reed warbler (Acrocephalus dumetorum) is a species of reed warbler belonging to the family Acrocephalidae, which also includes the tree warblers. Blyth's reed warbler breeds across the Palearctic zoogeographical region and winters in South Asia. The species has been expanding its range westwards in Europe.

It is classified in the reed warbler genus Acrocephalus which was formerly included in the polyphyletic family Sylviidae but is now included in the family Acrocephalidae.
