The slender-billed scimitar babbler (Pomatorhinus superciliaris) is a passerine bird in the Old World babbler family. It is found from the Himalayas to north-western Vietnam. Its natural habitat is subtropical or tropical moist montane forests. The slender-billed scimitar babbler was formerly placed in the monotypic genus Xiphirhynchus. It was moved to Pomatorhinus based on the results of a molecular phylogenetic study of the babblers published in 2009 that showed that it nested within a clade with other members of Pomatorhinus.
