Epipactis dunensis, commonly known as dune helleborine, is a species of plant in the orchid family Orchidaceae and is endemic to Great Britain and Ireland.

[1] It typically grows to a height of 20–50 cm (7.9–19.7 in) and the upper half of the flowering stalk is hairy.

The three sepals are greenish, the two petals paler, the lower part of the labellum (the hypochile) is boat-shaped and dark, chocolate brown with a transparent, whitish rim and the epichile is heart-shaped with a pointed tip.

[5][6] In 1926, Masters John Godfery raised the form to species status as Epipactis dunensis.

Some authorities refer to the Tyne helleborine that grows in woodland in northern England and southern Scotland.
