Pnoepyga is a genus of passerines endemic to southern and southeastern Asia. Its members are known as cupwings or wren-babblers. The genus contains four species. The genus has long been placed in the babbler family Timaliidae. A 2009 study of the DNA of the families Timaliidae and the Old World warblers (Sylviidae) found no support for the placement of the genus in either family, prompting the authors to erect a new monogeneric family, the Pnoepygidae.
