East Aberdeenshire was a Scottish county constituency of the House of Commons of the Parliament of the United Kingdom from 1868 to 1918 and from 1950 to 1983. It elected one Member of Parliament (MP) by the first past the post system of election.

Aberdeenshire or the County of Aberdeen is a historic county and registration county of Scotland. The area of the county, excluding the Aberdeen City council area itself, is also a lieutenancy area. The county borders Kincardineshire, Angus and Perthshire to the south, Inverness-shire and Banffshire to the west, and the North Sea to the north and east. It has a coast-line of 65 miles (105 km). The county gives its name to the modern Aberdeenshire council area, which covers a larger area than the historic county.
