The Scottish people or Scots are an ethnic group and nation native to Scotland. Historically, they emerged in the early Middle Ages from an amalgamation of two Celtic peoples, the Picts and Gaels, who founded the Kingdom of Scotland in the 9th century. In the following two centuries, Celtic-speaking Cumbrians of Strathclyde and Germanic-speaking Angles of 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.

Scots is an Anglic language variety in the West Germanic language family, spoken in Scotland and parts of Ulster in the north of Ireland. Most commonly spoken in the Scottish Lowlands, Northern Isles, and northern Ulster, it is sometimes called Lowland Scots to distinguish it from Scottish Gaelic, the Goidelic Celtic language that was historically restricted to most of the Scottish Highlands, the Hebrides, and Galloway after the sixteenth century; or Broad Scots to distinguish it from Scottish Standard English. Modern Scots is a sister language of Modern English, as the two diverged independently from the same source: Early Middle English (1100–1300).
