Leroi, Le Roi or Roi is a French given name and 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 the Old French roy, roi (French pronunciation: [ʁwa]), meaning "king", or "the king", which was a byname used before the Norman Conquest and a personal name in the Middle Ages.
