Tis was one of the most important commercial ports of Iran in the early and middle centuries of the Islamic era. It played an important role in maritime or caravan export and import. Not only is this port less mentioned in historical sources, but also little research has been done on it. One of the archaeological findings of this region is various ceramics from Islamic periods, which are distributed on different parts of the site. Except for brief references in a few sources, there has been no independent research on ceramics of Islamic periods of Tis. Accordingly, the main purpose of this study is to know the economic and social life of Tis port in the Islamic era through study, analysis, and chronology of pottery. The method of this research is descriptive-analytical. The information is collected through field and library studies. According to research, the ceramics of the Islamic periods of Tis, probably belong to the 7-17 th centuries, but most of them date back to the 9 th -12 th centuries. During this period, various types of glazed and unglazed ceramics were used in this area, some of which, such as unglazed red ware and Celadon, were probably imported from near and far areas such as India, China, and others like a group of Sgraffito were domestically produced.
