Material and methods: Using scientometrics approach, this paper studied co-authorship network of Iranian scientometrics researchers. The population includes 779 articles published both in English and Persian and indexed in 4th edition of scientometrics bibliography (last version till now) during 2002-2012. First, the co-authorship network matrix was drawn by using excel software second, the UCINET software and VOSviewer were used for data analysis.

 Findings: The study of co-authorship patterns of Iranian scientometrics researchers indicated that Farideh Osareh (47 articles), Mohammad Hasanzadeh (43 articles), and Albdolrreza NouruziChackoli (36 articles) have the highest rank among scientometrics researchers in scientific productivity. According to central indicator, Farshid Danesh (77), Albdolrreza NouruziChackoli (69), and Mohammad Hasanzadeh (66) had the most number of co-authorship with other researchers.

 Conclusion: Although clustering coefficient (= 0.767) showed the relative interest of this network members to work with each other and shaping different clusters, the density coefficient (=0.009) revealed the low consistency of the network.
