The sulphur-bearded reedhaunter (Limnoctites sulphuriferus) is a species of non-migratory bird in the family Furnariidae. It is found in the Pampas and adjacent areas of eastern Argentina, southern Uruguay, and Rio Grande do Sul, Brazil. Its natural habitats are marshes with dense reed beds. Previously included in the genus Cranioleuca, but genetic evidence revealed that L. sulphuriferus is the sister species of Limnoctites rectirostris.
