Hemigenia is a genus of flowering plants in the mint family, Lamiaceae and is endemic to Australia where most species occur in Western Australia, although some are also found in New South Wales and Queensland. Plants in this genus are shrubs or bushes with simple leaves and tube-shaped flowers with the petals forming two "lips" - the upper one with two lobes and the lower one with three.

Plants in the genus Hemigenia are shrubs or bushes with simple leaves which are arranged either in opposite pairs or in whorls. The flowers are arranged singly or in groups in upper leaf axils, often appearing to form a spike of flowers. There are five sepals which are joined at their base to form a tube. The five petals form a tube with two "lips" - an upper lip with two lobes and a lower one with three. There are four stamens.

Plants in this genus can be distinguished from those in the similar and closely related Hemiandra by their less strongly odoriferous leaves and from Prostanthera, Microcorys and Westringia by technical differences in their stamens.

The genus Hemigenia was first formally described in 1810 by Robert Brown and the description was published in Prodromus Florae Novae Hollandiae. Brown nominated Hemigenia purpurea the type species. The genus name is derived from the Ancient Greek words hemi and genias meaning "a beard" referring to a part of the anthers.
