The Southern African rock python (Python natalensis) is a large python species native to Southern Africa inhabiting savanna and woodland. It was first described by Andrew Smith in 1833.{{cite book |author=Smith, A. |year=1849 |title=Illustrations of the zoology of South Africa : consisting chiefly of figures and descriptions of the objects of natural history collected during an expedition into the interior of South Africa, in the years 1834, 1835, and 1836; fitted out by "the Cape of Good Hope Association for exploring Central Africa" : together with a summary of African zoology, and an inquiry into the geographical ranges of species in that quarter of the globe |location=London |publisher=Smith, Elder and Co |pages=42–44 |chapter=Python natalensis |chapter-url=https://archive.org/details/illustrationszo00smite/page/n41/mode/2up}} Growing a length of more than {{cvt|5|m|ft}}, this is one of the largest snakes in the world.

The Southern African rock python has a colouration that is similar to its northern relative, however it is described as being "drabber". Below the light stripe on both snakes' head, the southern species has a narrower dark patch that resembles a stripe instead of a patch. The Central African rock python (Python sebae) has two prominent light lines from the nose, over the eye to the back of the head, which are much duller in the Southern African rock python. The northern species has considerably larger head scales.{{Cite web |url= https://reptile-database.reptarium.cz/species?genus=Python&species=natalensis |title=Difference from P. sebae}}{{cite web|url=https://www.africansnakebiteinstitute.com/articles/snake-comparison-african-rock-python-vs-southern-african-python/#:~:text=The%20African%20Rock%20Python%20has,differences%20between%20the%20two%20species| title=Snake Comparison – African Rock Python vs Southern African Python| date=2019}} It is also noticeably inferior in size to size the Central African rock python.

In culture
In Where Men Still Dream, the South African journalist and author Lawrence G. Green speculates that the legend of the Grootslang, a mythical being in South African prospector folklore resembling a giant serpent and said to live in the Orange River, most likely originated from sightings of unusually large rock pythons in the river, which were exaggerated into descriptions of a monstrous being.{{cite book|author=Green, Lawrence George |title= Where Men Still Dream |date=1948 |url= https://archive.org/details/in.ernet.dli.2015.54893/page/n137/mode/2up |publisher= Standard Press Ltd., Cape Town |pages= 125–126}}
