Richard Fitzalan, 11th Earl of Arundel and 10th Earl of Surrey (1346 - September 21, 1397, beheaded) was an English nobleman and military commander.

He was the son of Richard Fitzalan, 10th Earl of Arundel and Eleanor of Lancaster.

In 1377 he was Admiral of the West and South, and in 1386 Admiral of all England. In this capacity he defeated a combined Franco-Spanish-Flemish fleet off of Margate in 1387. The following year he was one of the Lords Appellant to Richard II.

In 1397 he was arrested for his opposition to Richard II, and then attainted and beheaded.

Arundel married twice. His first wife was Elizabeth de Bohun, daughter of William de Bohun, 1st Earl of Northampton. They married around September 28, 1359 and had four children:

• Thomas Fitzalan, 12th Earl of Arundel
• Elizabeth D'Arundelle Fitzalan
• Joan Fitzalan (1375 - November 14, 1453), who married William Beauchamp, 1st Lord Bergavanny;
• Margaret Fitzalan, who married Sir Rowland Lenthall;
• Alice Fitzalan, who married the 4th Baron Charleton.

Arundel then married Philippa Mortimer, daughter of Edmund Mortimer, 3rd Earl of March. Her mother was Philippa Plantagenet, a daughter of Lionel of Antwerp and thus a granddaughter of Edward III. They had no children.
