Alexander Stewart (1214–1283), also known as Alexander of Dundonald, was 4th hereditary High Steward of Scotland from his father's death in 1246.

A son of Walter Stewart, 3rd High Steward of Scotland by his wife Bethóc, daughter of Gille Críst, Earl of Angus, Alexander is said to have accompanied Louis IX of France on the Seventh Crusade (1248–1254). In 1255 he was one of the councillors of King Alexander III, though under age.

He was the principal commander under King Alexander III of Scotland at the Battle of Largs, on 2 October 1263, when the Scots defeated the Norwegians under Haakon IV. The Scots invaded and conquered the Isle of Man the following year, which was, with the whole of the Western Isles, then annexed to the Crown of Scotland.

The identity of Alexander's wife is uncertain. Some secondary sources erroneously identify her as Jean, daughter of James, son of Angus, son of Somerled.

Through their eldest son James they were great-grandparents of King Robert II, the first Stewart to be King of Scots, and thus ancestors of all subsequent Scottish monarchs and the later and current monarchs of Great Britain.

Through their second son John, they were the direct ancestors in the male line of Henry Stuart, Lord Darnley, and of the Stuart monarchs of Scotland and England from Darnley's son James VI and I onwards.
