Aberdeenshire or the County of Aberdeen (Siorrachd Obar Dheathain in Gaelic) is a registration county of Scotland. This area (excluding Aberdeen itself) is also a lieutenancy area.

Aberdeenshire was a Scottish constituency of the House of Commons of the Parliament of Great Britain from 1708 to 1801 and of the Parliament of the United Kingdom from 1801 until 1868. It represented the county of Aberdeenshire, minus the burgh of Aberdeen.
