The Flag of Scotland, (Scottish Gaelic: Bratach nàiseanta na h-Alba,Scots: Banner o Scotland), also known as Saint Andrew's Cross or the Saltire, is the national flag of Scotland. As the national flag it is the Saltire, rather than the Royal Standard of Scotland, which is the correct flag for all individuals and corporate bodies to fly in order to demonstrate both their loyalty and Scottish nationality. It is also, where possible, flown from Scottish Government buildings every day from 8am until sunset, with certain exceptions.

According to legend, the Christian apostle and martyr Saint Andrew, the patron saint of Scotland, was crucified on an X-shaped cross at Patras, (Patrae), in Achaea. Use of the familiar iconography of his martyrdom, showing the apostle bound to an X-shaped cross, first appears in the Kingdom of Scotland in 1180 during the reign of William I. This image was again depicted on seals used during the late 13th century; including on one particular example used by the Guardians of Scotland, dated 1286.

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.
