The 1970-2006 Aabenraa municipality was bordered by the municipality of Lundtoft to the south and east, and Rødekro and Tinglev to the west. As it was partially located on a peninsula, it was surrounded by water on three sides: at the southern side of the peninsula by Aabenraa Fjord opening up to the Little Belt east of the peninsula; at the northern side by Genner Bay (Genner Bugt). in South Jutland County on the east coast of the Jutland peninsula in south Denmark.
