Hjørring is a town on the island of Vendsyssel-Thy at the top of the Jutland peninsula in northern Denmark. It is the main town and the administrative seat of Hjørring Municipality in the North Jutland Region. The population is 25,917. It is also one of Denmark's oldest towns, having celebrated its 750th anniversary as a market town in 1993.

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.
