Scottish Americans or Scots Americans (Scottish Gaelic: Ameireaganaich Albannach; Scots: Scots-American) are Americans whose ancestry originates wholly or partly in Scotland. Scottish Americans are closely related to Scotch-Irish Americans, descendants of Ulster Scots, and communities emphasize and celebrate a common heritage. The majority of Scotch-Irish Americans originally came from Lowland Scotland and Northern England 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. The number of Scottish Americans is believed to be around 25 million, and celebrations of Scottish identity can be seen through Tartan Day parades, Burns Night celebrations, and Tartan Kirking ceremonies.
