William, Earl of Ross (Gaelic: Uilleam; died c. 1323) was ruler of the province of Ross in northern Scotland, and a prominent figure in the Wars of Scottish Independence.

William was the only child of William I, Earl of Ross and his wife Jean Comyn, daughter of William, Earl of Buchan. He succeeded to the earldom on the death of his father in 1274. In 1284 he joined with other Scottish noblemen who acknowledged Margaret, Maid of Norway as the heir to the unfortunate Alexander III. Following Margaret's death, he sided alternately with the Scottish and English interests. In 1291 he paid homage to Edward I of England at Berwick recognising him as overlord of Scotland. He was chosen as an auditor at the trial between John Balliol and Robert Bruce, when they competed before Edward to decide who would take the throne of Scotland.

William was one of the leaders of the Scottish army at the Battle of Dunbar in 1296, when Edward invaded Scotland to punish John Balliol for refusing to support the English invasion of France. After the Scottish defeat, he was captured by the English and sent to the Tower of London, where he remained until September 1303, when an order was issued for his escort to Scotland. He reached Perth in December, and stayed there with Edward, Prince of Wales until he was sent home in February. Later in 1304 he was with King Edward at Dunfermline, who bestowed upon him a horse, armour, and other presents, as well as appointing him Warden beyond the Spey.

In 1306, Robert's wife Elizabeth, his daughter Marjorie, and other Bruce supporters took refuge from the advancing English army in the chapel of St Duthac at Tain in Ross, while on their way to the safety of Orkney. However, William violated the sanctuary, and had them arrested and handed over to the English. They were sent as prisoners to England where two of the women were caged outdoors for four years, and the women were not liberated until 1312.
