Xerothamnella parvifolia, also known as the Small-leaved Little Dry Shrub, is a species of plant in the acanthus family that is endemic to Australia.

The white and red flowers are about 10 mm long and occur in the upper leaf axils.

Flowering usually takes place from November to January, and sometimes in other seasons, when triggered by adequate rainfall.

[1] The species is found in the Channel Country IBRA bioregion, in south-western Queensland, Mount Poole in north-western New South Wales and in South Australia.

Threats include grazing and browsing by native and feral herbivores, as well as by mineral exploration activities.
