The Isdal woman (Norwegian: Isdalskvinnen) is the subject of an unsolved case involving an unidentified woman found dead at Isdalen Valley in Bergen, Norway on 29 November 1970. Considered one of Norway's most profound mysteries, the case has been the subject of intense speculation over the years regarding the identity of the victim, the events leading up to her death and the cause of death. Public interest in the case remains significant.

The woman was found in a part of Isdalen popularly known as "Death Valley", which lies in the direction towards Mount Ulriken. Next to the scene police found a burned-out passport. The autopsy showed that the woman had suffered blunt force trauma to the neck and had taken several sleeping pills before she died. The official police report concluded suicide, but this conclusion is highly controversial.

Discovery

On 29 November 1970 at approximately 13:15, while hiking in the hills of Isdalen valley outside of Bergen, a university professor and his two young daughters came across the partially charred remains of a naked woman hidden among some rocks at a remote hiking trail. Present at the scene were large amounts of sleeping pills, and bottles of petrol. A full scale murder investigation was immediately initiated and the case has since evolved to become the most comprehensive criminal case by the Bergen police.
