The North Jutlandic Island, Vendsyssel-Thy, or Jutland north of the Limfjord is the northernmost part of Denmark and of Jutland. It is more common to refer to the three traditional districts of Vendsyssel, Hanherred, and Thy. The area has been intermittently a tied island and, during modern times, was not surrounded by water until a storm in February 1825, which severed the region from the remainder of Jutland and caused a water connection between the North Sea and the western end of the Limfjord. Hence, it is traditionally regarded as a part of Jutland rather than a separate island.

Denmark is a Nordic country in the south-central portion of Northern Europe. It is the metropolitan part of and the most populous constituent of the Kingdom of Denmark, a constitutionally unitary state that includes the autonomous territories of the Faroe Islands and Greenland in the North Atlantic Ocean. Metropolitan Denmark is the southernmost of the Scandinavian countries, lying south-west and south of Sweden, south of Norway, and north of Germany, with which it shares a short border, Denmark's only land border.
