Anacamptis morio, the green-winged orchid or green-veined orchid (synonym Orchis morio), is a flowering plant of the orchid family, Orchidaceae. It usually has purple flowers, and is found in Europe, Northern Africa and western Asia.

It flowers from late April to June in the British Isles, and as early as February in other countries, such as France. The inflorescence is of various colours, mainly purple but ranging from white, through pink, to deep purple. From 5 to 25 helmet-shaped flowers grow in a loose, linear bunch at the top of the single stalk. A pair of lateral sepals with prominent green, occasionally purple veins extend laterally like "wings", giving the orchid its name. The broad, three lobed, lower petal is pale in the center with dark spots.

Leaves are lanceolate, or sometimes ovate, and grow in a rosette around the base of the plan, with some thinner leaves clasping the stem and sheathing almost up to the flowers. Leaves are green and unspotted. Plants grow to 40 cm in height.

It is similar in appearance to the early purple orchid Orchis mascula, which flowers around the same time of year, but Anacamptis morio has green stripes on the two lateral sepals, and lacks the spots or blotches of the Early Purple's leaves.

Individual plants may flower for up to 17 years.

The species was first described, as Orchis morio, by Carl Linnaeus, in 1753. It was transferred to the genus Anacamptis in 1997. Anacamptis comes from the Greek ανακάμτειν "anakamptein" which means to bend, although according to different sources it may mean to bend backward, to bend down or to bend forward. The name morio is Latin for "clown", which its striped and spotted flowers were held to resemble.

As of May 2014^[update], the World Checklist of Selected Plant Families accepts six subspecies:

It is a native of western Eurasia, ranging from Europe to Iran, and Northern Africa from Morocco to Tunisia. In the British Isles it is found in central-southern England, Wales and Ireland.
