Nørresundby (Danish pronunciation: [nɶɐ̯ɐˈsɔnˌpyˀ]) is a city in Aalborg Municipality, north of Limfjorden, in Vendsyssel, in Denmark.

Nørresundby is the site of the Lindholm Høje settlement and burial ground from the Germanic Iron Age and Viking times.

The city is connected to Aalborg by a road bridge Limfjordsbroen, as well as a motorway (E45) passing it to the east and running under the Limfjord.

The school offers the traditional three-year program but also the so-called Higher Preparatory Examination (HF), which takes two years to complete.

Nørresundby Gymnasium & HF is a certified Cambridge & Science school and it is furthermore open for exchange students.
