As redefined by the Fifth Periodical Review of the Boundary Commission for Scotland. and subsequently first used in the 2005 general election, it is one of five constituencies covering the Aberdeenshire council area and the Aberdeen City council area. To the northeast of West Aberdeenshire and Kincardine there are the constituencies of Aberdeen North and Aberdeen South, which are both entirely within the Aberdeen City area. To the north of West Aberdeenshire and Kincardine, there is the Gordon constituency, which covers part of the Aberdeenshire area and part of the Aberdeen City area, and further north there is the Banff and Buchan constituency which, like West Aberdeenshire and Kincardine, is entirely within the Aberdeenshire area.
The West Aberdeenshire and Kincardine constituency includes the towns of Stonehaven, Portlethen and Banchory, and stretches along the Dee river valley to Braemar. Westhill and Kemnay, which were with the Gordon constituency until 2005, are now within the West Aberdeenshire and Kincardine constituency.
