The sombre rock chat was formerly included in the genusCercomela. Molecular phylogenetic studies published in 2010 and 2012 found that the genus Cercomela was polyphyletic with five species, including the sombre rock chat, phylogenetically nested within the genus Oenanthe.[2][3] As part of a reorganization of the species to create monotypic genera, the sombre rock chat was moved to the genus Oenanthe.[4]
