William Malet (died c. 1121) was the third of his family to hold the honour of Eye and the lordship of Graville [fr] in Normandy.
Before 1066, the older William Malet was the Lord of Graville, in Normandy and is known to have fought at the Battle of Hastings, helping to secure the crown of England for William, Duke of Normandy.
The Malets were reputedly related by blood or marriage to both William the Conqueror and King Harold of England.
After his exile from England, Malet re-established himself in Normandy where he retained the Lordship of Graville.
His descendants rose to prominence in France through their military exploits for the French crown.
