Aberdeen South is a burgh constituency of the House of Commons of the Parliament of the United Kingdom and it elects one Member of Parliament (MP) by the first-past-the-post system of election. The constituency was first used in the 1885 general election, but has undergone boundary changes since then. There was also an Aberdeen South Holyrood constituency, a constituency of the Scottish Parliament, created in 1999 with the boundaries of the Westminster constituency at that time. In 2011 the Scottish Parliament constituency of Aberdeen South was abolished and replaced with the Aberdeen South and North Kincardine constituency.
