The Winifred's warbler (Scepomycter winifredae), also known as Mrs. Moreau's warbler, is a species of passerine in the Cisticolidae family. The genus Scepomycter has traditionally been considered monotypic, but in 2009 a closely related new species was described, the Rubeho warbler. Alternatively, the Winifred's warbler is sometimes included in the genus Bathmocercus. It is endemic to montane forest in the Uluguru Mountains in Tanzania. Populations in the Rubeho-Ukaguru Mountains are the very similar Rubeho warbler, and the status as vulnerable is for the "combined" species. It is threatened by habitat loss.
