The Drakensberg rockjumper or orange-breasted rockjumper (Chaetops aurantius) is a medium-sized insectivorous passerine bird endemic to the alpine grasslands and rock outcrops of the Drakensberg Mountains of southeastern South Africa and Lesotho.

The Cape rockjumper male has rufous red underparts, and the female and young are darker buff below than in C.

Breeding is often cooperative; one or two additional individuals, usually a pair's offspring of the preceding breeding season, may assist the parents in territorial defence and alarm calling, and in the feeding of nestlings and fledglings.

[3] Chaetops aurantius was described in 1867 by Edgar Leopold Layard in his book The birds of South Africa.

[5][6] Some authorities (notably Dickinson and Christidis) treat the two rockjumpers as a single species, Chaetops frenatus, with two subspecies.
