The Serra Antwren (Formicivora serrana) is a species of bird in the Thamnophilidae family. It is endemic to Rio de Janeiro, Espírito Santo and Minas Gerais in southeastern Brazil. It includes two subspecies: nominate and interposita. The latter closely resembles the Restinga Antwren, and recent morphological and vocal analysis suggests the Restinga Antwren should be included in the Serra Antwren.
