Communication plays a critical role in any sustainable plan or strategy. This meta-analysis was conducted to provide an overall perspective of the relationship between communication and organizational performance. A total of 999 articles in both English and Farsi were extracted from four databases. The random effects model was used to analyze the data. The analysis was done by CMA2 ) V2.2. 064 (. The results based on the random effects model illustrated that the degree of the relationship between communication and organizational performance is large, positive, and significant (R=0.745, CI=0.95 p=0.000%). Furthermore, "Research object", "publication year" and "country" were identified as moderator variables in this relationship. An important jump in the intensity of this relationship was detected from 2017. Moreover, a significant difference in the intensity of this relationship was observed in educational organizations with commercial and medical organizations, which can be useful for activists in these fields. The intensity of the relationship in the countries of China, Malaysia, USA, South Korea, and Iran have been evaluated as significantly different. Therefore, these results can open new horizons for future research and especially the localization of international research results.
