Hairy willow-herb is native to Eurasia, where it is found in moist waste ground of the Mediterranean region, Europe, Asia, and Africa. It is widespread, often forming large, long-lived colonies in England, Wales, and Ireland. In Scotland it is confined to the east coast. Intolerant of shade, hairy willow-herb is found in damp and waste places to elevations of 2500 meters
