Scottish may refer to something of, from, or related to Scotland, a country in northern Europe, part of the United Kingdom since 1707.

Scottish may also refer to:

Scottish Americans or Scots Americans (Scottish Gaelic: Ameireaganaich Albannach) are citizens of the United States whose ancestry originates wholly or partly in Scotland. Scottish Americans are closely related to Scots-Irish Americans, descendants of Ulster Scots, and communities emphasize and celebrate a common heritage. The majority of Scot-Irish originally came from the lowlands and border country of Scotland before migrating to the province of Ulster in Ireland (see Plantation of Ulster) and thence, beginning about five generations later, to North America in large numbers during the eighteenth century.

Recent studies state that there are between 30-40 million Americans who claim Scottish and Scot-Irish heritage in the United States. These figures include both Americans who claim Scottish heritage only as well as those who claim Scottish and other nationalities.

The first Scots in North America probably came with the Vikings. A Hebridean bard is said to have accompanied Bjarni Herjolfsson on his voyage around Greenland in 985 which sighted the mainland. On the evidence of the sagas, the first Scots to set foot in the New World were slaves, a man named Hake and a woman named Hekja, who scouted for Thorfinn Karlsefni's expedition in 1010, gathering wheat and the grapes for which Vinland was named. The controversial Zeno letters have been cited in support of a claim that Henry Sinclair, earl of Orkney, visited Nova Scotia in 1398. In the early years of Spanish colonization of the Americas, a Scot named Tam Blake spent 20 years in Mexico and Colombia and joined Coronado's 1540 expedition to the American Southwest.

The Scottish people (Scots Gaelic: Albannaich), or Scots, are a nation and ethnic group native to Scotland. Historically they emerged from an amalgamation of the Picts and Gaels, incorporating neighbouring Britons to the south as well as invading Germanic peoples such as the Anglo-Saxons and the Norse. Later the Normans also had some influence.

In modern use, "Scottish people" or "Scots" is used to refer to anyone whose linguistic, cultural, family ancestral or genetic origins are from within Scotland. The Latin word Scotti originally applied to a particular, 5th century, Goidelic tribe that inhabited Ireland. Though sometimes considered archaic or pejorative, the term Scotch has also been used for the Scottish people, though this usage is current primarily outside Scotland.

There are people of Scottish descent in many countries other than Scotland. Emigration, influenced by factors such as the Highland and Lowland Clearances, Scottish participation in the British Empire, and latterly industrial decline and unemployment, resulted in Scottish people being found throughout the world. Large populations of Scottish people settled the new-world lands of North and South America, Australia and New Zealand. There is a Scottish presence at a particularly high rate in Canada, which has the second largest population of descended Scots ancestry, after the United States. They took with them their Scottish languages and culture.
