Pedicularis dasyantha (woolly lousewort or arctic hairy lousewort) is a plant native to the high arctic areas of Svalbard, Novaya Zemlya and the bordering mainland, and the western Taymyr Peninsula. In Svalbard it is restricted to the main island, Spitsbergen. It grows in moist places and on heaths, often together with Dryas octopetala and Cassiope tetragona. Like all Pedicularis it is a hemiparasite and the preferred host is probably Dryas octopetala.
