Aarhus County or Århus County (Danish: Århus Amt) is a former county of Denmark (Danish: amt) on the Jutland peninsula. It was created in 1970 by the fusion of the Aarhus, Randers and Skanderborg counties. The county was abolished effective 1 January 2007, when almost all of it merged into Region Midtjylland (i.e. Region Central Jutland). A very small portion was merged into Region Nordjylland (Region North Jutland). At the time of its abolishment, more than 20,000 people worked for the county.
