Alexander Stewart of Darnley (died 1404)

Alexander Stewart of Darnley was a Scottish nobleman and soldier who played a significant role in Scottish politics during the late 14th century. He was the son of Sir John Stewart of Darnley and his wife, Isabella Lennox, daughter of Duncan, Earl of Lennox.

Stewart held the title of Lord of Darnley, inherited from his father. The Darnley lands were located in Renfrewshire, southwest of Glasgow. He was a prominent figure in the Lennox region and a close ally of his cousin, Duncan, Earl of Lennox.

Alexander Stewart is primarily remembered for his involvement in the ongoing power struggles between various noble factions within Scotland, particularly those involving the Stewarts. He was a strong supporter of Robert Stewart, Duke of Albany, who served as Regent of Scotland during the reigns of Robert II and Robert III.

Stewart participated in several military campaigns and skirmishes during this period. Details of his specific military exploits are sparse, but he was undoubtedly a key participant in the maintenance of Albany's power.

Alexander Stewart of Darnley died in 1404. His son, John Stewart of Darnley, succeeded him as Lord of Darnley and later became a Constable of the Scottish Army in France. The Darnley Stewarts eventually rose to greater prominence, with a descendant, Henry Stuart, Lord Darnley, marrying Mary, Queen of Scots.
