Eyjafjörður is the longest fjord in central northern Iceland. It is located in the second most populous region of Iceland. The name literally means: "Island Fjord" which is derived from Hrísey island.
The fjord is surrounded by hills and mountains on both sides but the mountains are considerably taller on the west side, in the mountain range of the Tröllaskagi peninsula. In the outer part of the fjord there are no lowlands along the coast as the steep hills roll directly into the sea. Further south in the fjord there are strips of lowland along both coasts; these are wider on the west side.
Several valleys lead from Eyjafjörður, most of them to the west where the two most significant are: Hörgárdalur and Svarfaðardalur. Dalsmynni is the only valley on the east side. However the greatest valley in Eyjafjörður is also called Eyjafjörður and runs directly south from the fjord itself. It is long and wide and home to one of Iceland's largest agricultural regions.
The island of Hrísey in the middle of Eyjafjörður is the second largest island of the coast of Iceland and often referred to as "The Pearl of Eyjafjörður".
The region of Eyjafjörður is Iceland's second most populous one after the greater Reykjavík area in Southwest Iceland. The total population of the region was approximately 24,000 in 2008 (excluding the town of Siglufjörður and the island of Grímsey that are often associated with Eyjafjörður but do not belong to it in geographical sense.)
The largest town by far is Akureyri, other settlements in the region are: Dalvík, Ólafsfjörður, Hrísey, Árskógssandur, Hauganes, Hjalteyri, Hrafnagil, Svalbarðseyri and Grenivík. Most of these settlements base their livelihood on fisheries and agriculture but Akureyri is a service center as well and the site of a growing university.
