Terenura is a genus of insectivorous passerine birds in the antbird family, Thamnophilidae. The genus was erected by the German ornithologists Jean Cabanis and Ferdinand Heine in 1860 with the streak-capped antwren as the type species. The name of the genus comes from the Ancient Greek words terēn for "soft" and oura for "tail". The genus contains two species: The genus formerly included an additional four species but these were moved to the newly erected genus Euchrepomis based on the results of a genetic study published in 2012.
