The University of Aberdeen (Scots: University o' 'Aiberdeen; abbreviated as Aberd. in post-nominals; Scottish Gaelic: Oilthigh Obar Dheathain) is a public research university in Aberdeen, Scotland. It is an ancient university founded in 1495 when William Elphinstone, Bishop of Aberdeen and Chancellor of Scotland, petitioned Pope Alexander VI on behalf of James IV, King of Scots to establish King's College, making it Scotland's third-oldest university and the fifth-oldest in the English-speaking world. Aberdeen is consistently ranked among the top 160 universities in the world and is ranked within the top 20 universities in the United Kingdom according to The Guardian, The Times and The Sunday Times.

The university comprises three colleges — King's College, Marischal College, and Christ's College — that are now mainly ceremonial. The university as it is currently constituted was formed in 1860 by a merger between King's College and Marischal College, a second university founded in 1593 as a Protestant alternative to the former. The university's iconic buildings act as symbols of wider Aberdeen, particularly Marischal College in the city centre and the crown steeple of King's College in Old Aberdeen. There are two campuses; the predominantly utilised King's College campus dominates the section of the city known as Old Aberdeen, which is approximately two miles north of the city centre. Although the original site of the university's foundation, most academic buildings apart from the King's College Chapel and Quadrangle were constructed in the 20th century during a period of significant expansion. The university's Foresterhill campus is next to Aberdeen Royal Infirmary and houses the School of Medicine and Dentistry as well as the School of Medical Sciences. Together these buildings form one of Europe's largest health campuses. The annual income of the institution for 2020–21 was £235.9 million of which £45.9 million was from research grants and contracts, with an expenditure of £228.6 million.

Abertay University (Scottish Gaelic: Oilthigh Obar Thatha, formerly the University of Abertay Dundee, is one of two public universities in the city of Dundee, Scotland. In 1872, Sir David Baxter, 1st Baronet of Kilmaron, left a bequest for the establishment of a mechanics' institute in Dundee and the Dundee Institute of Technology was formed in 1888. As early as 1902 it was recognised by the Scottish Education Department as an educational hub, and was one of the first to be designated a central institution, akin to an "industrial university". Abertay gained University status in 1994.

Abertay launched the world's first computer games degree in 1997 and in 2017 held a programme of events celebrating 20 Years of Games. Abertay was also the first to offer a degree in Ethical Hacking, starting in 2006.
