Aberdeen South was a constituency of the Scottish Parliament (Holyrood).

Also, however, it was one of nine constituencies in the North East Scotland electoral region, which elected seven additional members, in addition to nine constituency MSPs, to produce a form of proportional representation for the region as a whole.

The other eight constituencies of the North East Scotland region were; Aberdeen Central, Aberdeen North, Angus, Banff and Buchan, Dundee East, Dundee West, Gordon and West Aberdeenshire and Kincardine.

In 2005, however, the boundaries of the Westminster (House of Commons) constituency were subject to some alteration.

Following their First Periodic review of parliamentary constituencies to the Scottish Parliament, the Boundary Commission for Scotland has created three newly shaped seats for the Aberdeen City council area.
