Scots (endonym: Scots; Scottish Gaelic: Albais, Beurla Ghallta) is an Anglic language variety in the West Germanic language family, spoken in Scotland and parts of Ulster in the north of Ireland (where the local dialect is known as Ulster Scots). 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 (1150–1300).

Scots is recognised as an indigenous language of Scotland by the Scottish government, a regional or minority language of Europe, as well as a vulnerable language by UNESCO. In the 2011 Scottish Census, over 1.5 million people in Scotland reported being able to speak Scots.

As there are no universally accepted criteria for distinguishing a language from a dialect, scholars and other interested parties often disagree about the linguistic, historical and social status of Scots, particularly its relationship to English. Although a number of paradigms for distinguishing between languages and dialects exist, they often render contradictory results. Broad Scots is at one end of a bipolar linguistic continuum, with Scottish Standard English at the other. Scots is sometimes regarded as a variety of English, though it has its own distinct dialects;^: 894 other scholars treat Scots as a distinct Germanic language, in the way that Norwegian is closely linked to but distinct from Danish.^: 894
