John de Mowbray, 4th Duke of Norfolk, KG (18 October 1444 – 14 January 1476), known as 1st Earl of Surrey between 1451 and 1461, was the only son of John de Mowbray, 3rd Duke of Norfolk and Eleanor Bourchier. His maternal grandparents were William Bourchier, Count of Eu and Anne of Gloucester.
In 1451 the earldom of Surrey was revived for him. Mowbray was descended from a sister of the last earl of the previous creation.
In 1461 he succeeded his father as 4th Duke of Norfolk and hereditary Earl Marshal. He continued his father's efforts to possess Caister Castle, finally taking it in September 1469 after a siege. He was invested a Knight of the Garter in 1472.
He was married to Elizabeth Talbot, daughter of John Talbot, 1st Earl of Shrewsbury and his second wife Lady Margaret Beauchamp. They had only one child, Anne de Mowbray, 8th Countess of Norfolk and so the 1397 creation of the dukedom became extinct upon his death. Anne, who was only 3 years old when her father died, inherited his extensive lands and wealth.
The dukedom would be recreated in 1481 and again in 1483, which survives to the present day.
