Aberdeenshire (Scottish Gaelic: Siorrachd Obar Dheathain) is one of the 32 council areas of Scotland.

It takes its name from the old County of Aberdeen which had substantially different boundaries. Modern Aberdeenshire includes all of what was once Kincardineshire, as well as part of Banffshire. The old boundaries are still officially used for a few purposes, namely land registration and lieutenancy.

Aberdeenshire Council is headquartered at Woodhill House, in Aberdeen, making it the only Scottish council whose headquarters are based outwith its jurisdiction, as Aberdeen itself forms a different council area (Aberdeen City). Aberdeenshire borders Angus and Perth and Kinross to the south, and Highland and Moray to the west.

Traditionally, it has been economically dependent upon the primary sector (agriculture, fishing, and forestry) and related processing industries. Over the last 40 years, the development of the oil and gas industry and associated service sector has broadened Aberdeenshire's economic base, and contributed to a rapid population growth of some 50%. since 1975, while the land covered represents 8% of Scotland's overall territory. It covers an area of 6,313 square kilometres (2,437 sq mi).
