Hjørring County (Danish: Hjørring Amt) is a former province in Denmark, located on the northern tip of Jutland and encompassing most of the island of Vendsyssel-Thy and the island of Læsø.
The region belonged to Vendsyssel during the Middle Ages.
In 1542, the north Jutland region was reorganised as Aalborghus Len.
The latter province was divided again in 1793 and the bulk of its territory was reorganised as Hjørring County.
