Using an altmetric study, this paper tries to investigate the visibility and activities of Iranian Library and Information Science (LIS) departments in ResearchGate. The research community of this study consisted of faculty members of LIS departments in Iran. Research data were analyzed by Altmetrics indicators from ResearchGate and then it is analyzed by SPSS software. Findings revealed that “University of Isfahan” with the mean score of 14.11 and standard deviation of 6.72 is ranked first and “Islamic Azad University of Hamedan” and “Tabriz University of Medical Sciences” ranked second and third, respectively. Also, the “University of Isfahan” ranked first in terms of research items, and “Shahid Beheshti University” and “Payame Noor University” ranked second and third, respectively. In terms of citations, “Farideh Osareh”, “Alireza Esfandiari-Moghadam” and “Amin Erfanmanesh” are the most-cited researcher in ResearchGate. Furthermore, “Alireza Esfandiari-Moghaddam” with RG score of 28.28, “Ali Akbar Khasseh” with the score of 24.96, and “Hajar Sotudeh” with the score of 20.26 have gained the highest scores in ResearchGate. In terms of number of readings, “Rahim Alijani”, “Asefeh Asemi”, and “Ali Akbar Khasseh” have the highest readings. In general, the results of this study showed that faculty members of LIS departments in Iran are far from the desired position in case of presence and activity in ResearchGate. Accordingly, in order to reach the desired position, by continuity and encouragement of other members they can achieve a suitable position.
