Pterostylis coccina, commonly known as the scarlet greenhood, is a species of orchid endemic to eastern Australia. As with similar greenhoods, the flowering plants differ from those which are not flowering. The non-flowering plants have a rosette of leaves flat on the ground but the flowering plants have a single flower with leaves on the flowering spike. In this species, the rosette leaves are relatively large and dark green, and the flowers are white, and bluish-green or red. It grows in New South Wales and north-eastern Victoria.
