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.

He continued his father's efforts to possess Caister Castle, finally taking it in September 1469 after a siege.

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 the earldom and his extensive lands and wealth.
