The Scots (Scots: Scots Fowk; Scottish Gaelic: Albannaich) are an ethnic group and nation native to Scotland. Historically, they emerged in the early Middle Ages from an amalgamation of two Celtic-speaking peoples, the Picts and Gaels, who founded the Kingdom of Scotland (or Alba) in the 9th century. In the following two centuries, the Celtic-speaking Cumbrians of Strathclyde and the Germanic-speaking Angles of north Northumbria became part of Scotland. In the High Middle Ages, during the 12th-century Davidian Revolution, small numbers of Norman nobles migrated to the Lowlands. In the 13th century, the Norse-Gaels of the Western Isles became part of Scotland, followed by the Norse of the Northern Isles in the 15th century.

In modern usage, "Scottish people" or "Scots" refers to anyone whose linguistic, cultural, family ancestral or genetic origins are from Scotland. The Latin word Scoti originally referred to the Gaels, but came to describe all inhabitants of Scotland. Considered pejorative by some, the term Scotch has also been used for Scottish people, now primarily outwith Scotland.

People of Scottish descent live in many countries. Emigration, influenced by factors such as the Highland and Lowland Clearances, Scottish emigration to various locales throughout the British Empire, and latterly industrial decline and unemployment, have resulted in the spread of Scottish languages and culture. Large populations of Scottish people settled the 'New World' lands of North and South America, Australia and New Zealand. The highest concentrations of people of Scottish descent in the world outside of Scotland are in Nova Scotia and Prince Edward Island in Canada, Otago and Murihiku/Southland in New Zealand, the Falkland Islands, and Northern Ireland in the United Kingdom. Canada has the highest level of Scottish descendants per capita in the world and the second-largest population of Scottish descendants, after the United States.
