The African reed warbler (Acrocephalus baeticatus) is an Old World warbler in the genus Acrocephalus. It is found in Iberia and over large parts of African. Some authorities consider this species as a subspecies of the Common reed warbler (Acrocephalus scirpaceus).
The adult has an unstreaked brown back and buff underparts. The forehead is flattened, and the bill is strong and pointed. The sexes are identical, as with most warblers, but young birds are richer buff below. The common reed warbler looks similar to the great reed warbler, but the great reed warbler is larger in size and has a stronger supercilium.
The song is a slow, chattering jit-jit-jit with typically acrocephaline whistles and mimicry added.
