John Mowbray, 4th Duke of Norfolk (18 October 1444 – 14 January 1476), 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 duke of Norfolk, and continued his father's efforts to possess Caister Castle, finally taking it in September 1469 after a siege.

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 Mowbray and so the dukedom became extinct upon his death. Anne was only 3 years old when her father died. She then inherited his extensive lands and wealth.
