Carpobrotus muirii (commonly known as dwarf sourfig or Dwerg Suurvy) is a succulent perennial of the family Aizoaceae, native to the Overberg region in the Western Cape, South Africa.

[1] Of the other six Carpobrotus species which occur in South Africa, this species is particularly closely related to Carpobrotus deliciosus, which has a similar shaped receptacle, but the latter is a much larger plant that occurs further to the east, mainly in the Eastern Cape.

[2] This species has a small distribution range, being restricted to the Overberg region in the Western Cape, South Africa.

Its sweet edible fruits are grazed by tortoises and other southern African animals, and are also used locally to make traditional preserves.

Its natural range is declining due to alien invasive species and wheat farming.
