Pyrorchis, commonly known as beak orchids, is a genus of flowering plants in the orchid family, Orchidaceae and is endemic in Australia. It contains two species which were previously included in the genus Lyperanthus, also known as beak orchids. Both species have fleshy, oval leaves and form colonies which flower profusely after bushfires.

Orchids in the genus Pyrorchis are terrestrial, perennial, deciduous, sympodial herbs with a few inconspicuous, fine roots and an oval-shaped tuber lacking a protective sheath. Replacement tubers are formed on the end of long, thin root-like stolons. There are between one and three broad, fleshy, egg-shaped to heart-shaped leaves at the base of the plant. The leaves are 2–14 cm (0.8–6 in) long, 2–8 cm (0.8–3 in) wide and bright green, sometimes with black markings.

There are up to eight resupinate flowers on a stalk 10–30 cm (4–10 in) high. The stalk is often surrounded by two or three loose, leaf-like bracts up to 4 cm (2 in) long. The sepal is lance-shaped, about 20 mm (0.8 in) long and forms a hood over the column. The sepals are about the same length and the same size and shape as the petals. As is usual in orchids, one petal is highly modified as the central labellum. The labellum is gently curved near its base where it encloses the base of the column but more strongly curved near its tip, which is deeply fringed. The column is about 12 mm (0.5 in), straight or gently curved with the anther at its tip. Flowering occurs between August and early December, depending on species and the fruit that follows flowering is a non-fleshy, dehiscent capsule containing up to 500 seeds.
