Hvisselhøj (also Vissehøj or Visihøj) is a 1915 excavated passage grave (Danish Jættestue) with three parallel chambers. Its construction is unique and only has a counterpart in Malta. It is located in Han Herred, in an intact mound of earth, north of the Limfjord on Alsbjergvej near Attrup on the island of Vendsyssel-Thy in Denmark.
It is a Neolithic (3500-2800 BC) megalithic structure of the Funnel Beaker Culture (TBK).
