Background: Workplace violence is one of the major health concerns and managerial issues that, by creating insecurity at the workplace, would affect the performance of the health personnel and their professional relations. Due to the close contact with patients and their companions, nurses are more exposed to workplace violence. The aim of the present study was to determine the prevalence of workplace violence against Iranian nurses. Methods: In the present systematic review and meta -analysis, 22 Iranian articles, which were published in Farsi and English until February 2017, were selected. National and international databases were searched using "nursing", "aggression", "physical violence", "verbal violence", and "workplace violence" keywords and their possible combinations. Data were analyzed using meta -analysis and random effects model. Heterogeneity between the studies was evaluated using I 2 test.
