One of the important sites of the Seleucid period in Iran is Laodicea in Hamadan province. This site was subjected to systematic survey and archaeological excavations during the years 2004, 2010 and 2021; A part of the cultural data of the excavation determined that the site was reused in the later especially the Islamic periods. In this article, Islamic glazed pottery obtained from three seasons of archaeological excavations has been carefully studied and a comprehensive classification has been prepared. Considering that the importance of the site was more in the historical period, conducting this research can help in clarifying the status of the site in the Islamic period as well as the position of Hamedan in the production of medieval Islamic period. The present research has been done by field studies (description, photography, design, classification and typology) and library studies (comparative studies and relative chronology). The results of the research show that this region was of special importance in the medieval Islamic period due to its location on the highway from Baghdad to Khorasan, and this factor caused the creation of many cultural connections with other regions, the evidence of which has appeared in the characteristic pottery of this region.
