Rinzia orientalis, commonly known as desert heath-myrtle,[2] is a species of flowering plant in the family Myrtaceae and is endemic to south-eastern Australia.

It is a shrub with elliptic to narrowly oblong leaves and white or pale pink flowers usually with ten stamens.

Rinzia orientalis is a shrub that typically grows to a height of 20–75 cm (7.9–29.5 in) and is usually single-stemmed at the base.

[2][3] The species was first formally described in 1838 by John Lindley who gave it the name Baeckea crassifolia in Thomas Mitchell's book Three Expeditions into the interior of Eastern Australia.

The specific epithet (orientalis) means "pertaining to the east" referring to the species' distribution compared to other members of the genus.
