John Holland, 2nd Duke of Exeter, 2nd Earl of Huntingdon (29 March 1395 – 5 August 1447) was an English nobleman and military commander during the Hundred Years' War.

The Holland family estates and titles were forfeited, but John was able to recover them by dedicating his career to royal service.

[4] Holland rendered great assistance to his cousin Henry V in his conquest of France, fighting both on land and on the sea.

Over the next five years he held various important commands with the English forces in France and in 1420 was made Constable of the Tower of London.

[citation needed] William, Thomas and Robert, the so-called "Bastards of Exeter", were active in the Lancastrian struggles, and Stow reported that two of them were among the notable dead at the Battle of Towton.
