Portulacaria pygmaea (previously Ceraria pygmaea), also known as the pygmy porkbush, is a small-leaved dwarf succulent plant found on the border between Namibia and the Cape Provinces of South Africa.

It is a small, compact, soft-wooded, dwarf shrub with Unisexual flowers (dioecious).

Its tiny compact branches spread, and often droop, staying close to the ground.

It also develops a thick caudex or root-stock, which has led to it being a popular bonsai specimen.

Within the genus Portulacaria it is most closely related to its larger sister-species Portulacaria fruticulosa.
