James Stewart, Duke of Ross (March 1476 – January 1504) was the son of King James III of Scotland and Margaret of Denmark.
He was made Marquess of Ormond at his baptism. He was created Earl of Ross in 1481 after its forfeiture to the crown by John, Lord of the Isles, this was then raised to Duke of Ross on his brother's accession in 1488. Ross had been their father's favourite, and the increasing preference shown to Ross- in particular his father's effort to marry him to Edward IV's daughter, Catherine of York- was a factor in his elder brother's rebellion against their father, and no doubt also explains James IV's later suspicions of his brother's loyalty.
Around May 1497 his elder brother King James IV nominated the twenty year old as Archbishop as it would decrease the chances that James, Duke of Ross would rebel against him. Also since James of Ross was only twenty and under age he could not use the archbishop revenues which his brother the King could use.
And he also became Lord Chancellor of Scotland in 1502.
He was one of three brothers, his two brothers being King James IV of Scotland and John Stewart, Earl of Mar.
