In this paper, 60 cemeteries of High and Late Middle Ages were processed in Northern Dalmatia, covering the area of Zadar and Šibenik - Knin County. The cemeteries of High (12th - 13th century) and the Late Middle Ages (14th - 15th century) corresponded to the stylistic Romanesque and Gothic period and with the time when dynasties of Arpads, Anjou, and Jagiellonian ruled in Croatia and Venetian Republic in Dalmatia. A general overview of the basic data was made for each cemetery individually. During the analysis of the grave architecture, differences between the graves of the High and the Late Middle Ages were noticed. The grave architecture of the High Middle Ages continues from the previous phase of the Early Middle Ages, built for a single burial, while the grave architecture of the Late Middle Ages is different from the previous phase because of its adaptation to the burial for more people. Although the medieval population was buried primarily by the churches, within the Christian customs, in the graves, and on the tombstones were found survivals of pagan traditions, which are partly related to the new Vlah population in the Late Middle Ages. Within the graves of High and Late Middle Ages, jewellery is the most found object, then dress accessories and finds such as swords, knives, coins, jewellery, ceramics, glass, etc. The analysis of the cemeteries was based on the current level of excavations and the state of publication of the research results.
