James Stewart, 3rd Earl of Moray (c. 1556–1592), was a Scottish nobleman and a prominent figure in the political landscape of 16th-century Scotland. He was the son of James Stewart, 2nd Earl of Moray and Mary Fleming, and he became the Earl after his father's death. His tenure was marked by his involvement in the conflicts between the Protestant and Catholic factions during the Scottish Reformation. As a supporter of the Protestant cause, Moray played a significant role in the power struggles of the time, including the Mary, Queen of Scots controversy. He was appointed as a regent for the young King James VI of Scotland after the abdication of Mary. His leadership was characterized by efforts to stabilize the country amidst ongoing religious and political turmoil.
