Aabenraa County (Danish: Åbenrå Amt, former spelling: Aabenraa Amt) is a former province in Denmark, located on the east-central region of Southern Jutland.

Aabenraa County was established in 1920 following the reunification of Denmark and South Jutland following the Schleswig Plebiscites.

Aabenraa County corresponded geographically to the former Prussian Kreis Apenrade combined with the larger part of Bov Parish and Frøslev municipality (Handewitt / Hanved Parish).

Both were transferred from Kreis Flensburg with the establishment of the current Danish-German border.

Aabenraa-Sønderborg County was dissolved in the 1970 administrative reform and the former Aabenraa County became seven new municipalities belonging to South Jutland County: This article incorporates material from the corresponding article on the Danish Wikipedia, accessed 30 April 2007.
