The Bristled Grassbird, Chaetornis striatus, is a passerine bird making up the monotypic genus Chaetornis. Chaetornis striata is endemic to the Indian subcontinent, where it is patchily and locally distributed in India, Nepal, and Pakistan. Formerly described as common in at least Gujarat, Andhra Pradesh and West Bengal (India) and parts of Bangladesh, it has declined.
Formerly placed in the "Old World warbler" family Sylviidae, its true affiliations have not been restudied. From its external morphology, it might belong to the newly-established grass warbler family Megaluridae.
