Romsdalen is a valley in Norway. The long valley runs through Rauma Municipality in Møre og Romsdal county and Lesja Municipality in Oppland county. It is the valley of the Rauma river, from old norse Raumsdalr (Rauma valley). The traditional district of Romsdal, which makes up about one-third of Møre og Romsdal county, is named for the valley of Romsdalen. The main road E136 and the Rauma line runs along the valley floor.
Mannen is an unstable rock above the valley. Mannen is expected to slide into the valley floor and block the river, there can be devastating flood downstream if the river suddenly breaks through the dam created by the rockslide. Around Remmem and Flatmark the valley is littered with huge rocks or boulders.
Trolltindene and other summits on the western edge are protected as part of Reinheimen National Park. Alpine summits around Isterdalen and Trollstigen are partly within the national park, partly within Trollstigen protected landscape area.
