Deroy or De Roy is a given name and French surname of Norman origin.

In France, this family name originated from the Normans, the descendants of Norse Vikings who migrated to Amigny, a commune in Manche, Normandy. The derivation is from de meaning "of" and the Old French roy, roi (French pronunciation: [ʁwa]), meaning "king", which was a byname used before the Norman Conquest and a personal name in the Middle Ages.

Earliest references cite Guillaume de Roy (William of Roy), who was a knight of the Knights Templar and one of several knights and feudal lords (seigneur) of the Roy family in France and Switzerland.

De Roy may also be a Dutch surname, being an Americanized or Flemish variant of De Rooij. Notable people with the name include:
