Prostanthera nivea, commonly known as snowy mint-bush,[2] is a species of flowering plant in the family Lamiaceae and is endemic to eastern Australia.

It is a shrub with linear to cylindrical leaves and white flowers arranged in leaf axils near the ends of branchlets and is one of the mint-bushes that is not aromatic.

The flowers are arranged in leaf axils near the ends of branches with bracteoles that are inconspicuous or up to 4 mm (0.16 in) long at the base.

[5][6] Bentham described two varieties and the names are accepted by the Australian Plant Census: Snowy mint-bush grows in forest, woodland and heath in south-eastern Queensland, eastern New South Wales and Victoria.

Subspecies induta grows in rocky crevices or on ledges in the Warrumbungles with a single collection from the Pilliga forest.
