The southern grey-headed sparrow (Passer diffusus) is a passerine bird of the sparrow family Passeridae.

It is sometimes treated as a subspecies of the grey-headed sparrow.

It is found in savanna and woodland in Angola and Zambia southwards into South Africa, where it is expanding its range[2] and is kept as a caged bird, like its relative the white-rumped seedeater.
