Kudurru was a type of stone document used as boundary stones and as records of land grants to vassals by the Kassites in ancient Babylonia between the 16th and 12th centuries BCE. The word is Akkadian for "frontier" or "boundary" (cf. Hebrew גדר "gader", fence, boundary; Arabic جدر "jadr", جدار "jidar" 'wall'; pl. جدور "judūr").
