Alexander Stewart, Duke of Albany (c. 1454 – 7 August 1485), was a Scottish prince and the second surviving son of King James II of Scotland.

Some of his actions on the marches aroused suspicion, suggesting sharp practice and a policy of border violence and truce breaking against England that contravened the 1474 marriage alliance of his brother King James III.

[3] Albany fled by sea to Paris where in September 1479 he was welcomed by King Louis XI, and received royal favour by his marriage to Anne de la Tour.

With the Duke of Gloucester, afterwards King Richard III, he marched at the head of one of the largest English armies to be assembled after the Wars of Independence – 20,000 men – to Berwick, which was seized (the last time it would change hands between England and Scotland) and then, with a smaller force, to Edinburgh.

It has been suggested that there was a conspiracy between Albany and a group of magnates who had been excluded from power in the 1470s, including the king's Stewart half-uncles, the earls of Atholl, Buchan and the bishop-elect of Moray, although evidence is limited.

Edward IV promised the duke further aid on 11 February, and on 19 March he managed to force the king into a humiliating indenture.

[3] With the death of Edward IV on 9 April 1483 Albany lost his main source of power and shortly thereafter he fled south, letting an English garrison into Dunbar Castle as he went.

Albany fled for the last time, again to France, where he was killed shortly afterwards in a duel with the duke of Orléans in Paris, by a splinter from the latter's lance.
