Common stonechat is the name used for the Saxicola species Saxicola torquatus when this is treated in its broad sense.
It is, however, now more widely considered to be a superspecies consisting of several related but distinct species,<ref>IOC World Bird List Template:Webarchive and references cited therein</ref> which are outwardly fairly similar but genetically distinct and replacing each other geographically without significant hybridisation:<ref name=Urquhart>Urquhart, E., & Bowley, A.

Three other species, not previously included within the broad view of common stonechat, have also been shown to be members of the superspecies:<ref name=Urquhart/><ref name=Illera>Illera, J.

- Fuerteventura chat Saxicola dacotiae
- Reunion stonechat Saxicola tectes
- White-tailed stonechat Saxicola leucurus
Species status possible,<ref name=Urquhart/> but not yet verified:
- Ethiopian stonechat Saxicola (torquatus) albofasciatus
Not all of the above are currently recognised as full species by all of the relevant taxonomical authorities, for example the British Ornithologists' Union,<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> currently include stejnegeri as a subspecies of Saxicola maurus.<ref> BOU Records Committee [1], September 2011.</ref>
