The North Jutlandic Island , Vendsyssel-Thy, or simply Jutland north of the Limfjord (Jylland nord for Limfjorden) are lesser-used names for the northernmost part of Denmark and of Jutland. It is more common to refer to the three traditional districts Vendsyssel, Hanherred and Thy. Although the area is separated from mainland Jutland by the Limfjord, it is traditionally regarded as a part of Jutland rather than an island.
