Hamadan province at western Iran is one the richest cultural region of Iran, as appear in numerous numbers of cultural and historical remains and sites. Rock arts are among the most important cultural, historical evidences of Hamadan province, while, until recently, there were only two sites of Darreh Divin of Alvand and Kamar Nebeshteh of Tuyserkan. However, the authors of present paper, with other researchers, introduced several sites of rock arts at different regions of the province, considering significance of rock arts at archaeological studies. There are different problems through research processes of rock arts at Hamadan province including unknown location, destruction, interpretation, and chronology of rock arts. The authors attempt to present research strategies in order to introduce, interpret, and chronology of rock arts of Hamadan province; based on field works and bibliographical studies. Conclusions indicate that there have been identified more than ten sites of rock arts including Azandaryan, Doustali, Qeshlaq, Argas, Arzanfoud, Ali Abad, Tarik Darreh that mostly relate to Alvand Mountain and its montane valleys. They could be date using stylistic and Semiological patterns, considering absence of laboratory facilities; furthermore, it demands ethnoarchaeological researches (migratory routes, identification of summer and winter residences), further any other subjects, to interpret rock arts.
