Aberdeen ⁱ/æbərˈdiːn/ (Scots: Aiberdeen  listen (help·info); Scottish Gaelic: Obar Dheathain [ˈopər ˈʝɛhɪn]) is Scotland's third most populous city, one of Scotland's 32 local government council areas and the United Kingdom's 29th most populous city, with an official population estimate of 220,420.

Nicknames include the Granite City, the Grey City and the Silver City with the Golden Sands. During the mid-18th to mid-20th centuries, Aberdeen's buildings incorporated locally quarried grey granite, whose mica deposits sparkle like silver. The city has a long, sandy coastline. Since the discovery of North Sea oil in the 1970s, other nicknames have been the Oil Capital of Europe or the Energy Capital of Europe. The area around Aberdeen has been settled since at least 8,000 years ago, when prehistoric villages lay around the mouths of the rivers Dee and Don.

Aberdeen received Royal Burgh status from King David I (1124–53), transforming the city economically. The city's two universities, the University of Aberdeen, founded in 1495, and The Robert Gordon University, which was awarded university status in 1992, make Aberdeen the educational centre of the north-east. The traditional industries of fishing, paper-making, shipbuilding, and textiles have been overtaken by the oil industry and Aberdeen's seaport. Aberdeen Heliport is one of the busiest commercial heliports in the world and the seaport is the largest in the north-east of Scotland.

Scotland (Scottish Gaelic: Alba ([ˈalˠ̪apə]  listen (help·info))) is a country that is part of the United Kingdom. Occupying the northern third of the island of Great Britain, it shares a border with England to the south and is bounded by the North Sea to the east, the Atlantic Ocean to the north and west, and the North Channel and Irish Sea to the southwest. In addition to the mainland, Scotland constitutes over 790 islands including the Northern Isles and the Hebrides.

Edinburgh, the country's capital and second largest city, is one of Europe's largest financial centres. Edinburgh was the hub of the Scottish Enlightenment of the 18th century, which transformed Scotland into one of the commercial, intellectual and industrial powerhouses of Europe. Glasgow, Scotland's largest city, was once one of the world's leading industrial cities and now lies at the centre of the Greater Glasgow conurbation. Scottish waters consist of a large sector of the North Atlantic and the North Sea, containing the largest oil reserves in the European Union. This has given Aberdeen, the third largest city in Scotland, the title of Europe's oil capital.
