Prostanthera eungella is a species of flowering plant in the family Lamiaceae and is endemic to the Eungella region in Queensland. It is an erect shrub with narrow egg-shaped leaves with small teeth, and mauve flowers that are white inside the petal tube and arranged in upper leaf axils.

Description
Prostanthera eungella is an erect shrub that typically grows to a height of about 1 m with hairy, glandular stems. The leaves are dark green, paler on the lower surface, narrow egg-shaped, 40–45 mm long and 10.5–11.5 mm wide on a petiole about 4 mm long. There are up to six teeth up to 0.5 mm long on the sides of the leaves. The flowers are arranged singly or in pairs in six to twenty leaf axils near the ends of branchlets, each flower on a pedicel 2–4 mm long. The sepals are green, densely glandular and form a tube 2.5–3 mm long with two lobes, the lower lobe 2–2.5 mm long 4 mm wide and the upper lobe about 2 mm long. The petals are 10–12 mm long, mauve and white inside the petal tube. The lower lip has three lobes, the centre lobe broadly spatula-shaped, 6–8 mm long and about 7 mm wide, the side lobes about 4.5 mm long and 2.5 mm wide. The upper lip is 4.5 mm long and about 7.5 mm wide with a central notch 1–1.5 mm deep. Flowering has been recorded in May and December.
