Pterostylis tenuissima, commonly known as the swamp greenhood, is a species of orchid endemic to the southern mainland of 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. This greenhood has small translucent white flowers with dark green stripes and markings and both the dorsal sepal and lateral sepals have relatively long, thread-like tips.
