Elythranthera, commonly known as enamel orchids, is a genus of flowering plants in the orchid family, Orchidaceae. It contains two species and a named hybrid, all endemic to Western Australia.

Orchids in the genus Elythranthera are terrestrial, perennial, deciduous, sympodial herbs with a few inconspicuous, fine roots and a tuber partly surrounded by a fibrous, multi-layered protective sheath. Like orchids in the genus Cyanicula, the tuber does not produces "droppers" - instead replacing itself within the same cavity. There is a single hairy convolute leaf at the base of the plant. The leaf is narrow egg-shaped, 2–8 cm (0.8–3 in) long, about 7 mm (0.3 in) wide, simple and lacks lobes and serrations.

There are up to four resupinate flowers on a stalk 12–30 cm (5–10 in) high. The three sepals and two petals are free and similar in size and shape to each other. They are glossy and pink to purple in colour. As is usual in orchids, one petal is highly modified as the central labellum. The labellum is small and with two large, black calli. The sexual parts of the flower are fused to the column, which has broad, wing-like structures forming a hood over the stamen and stigma. Flowering occurs from late winter to early summer, depending on species. The fruit that follows flowering is a non-fleshy, dehiscent capsule containing up to 500 seeds.
