Abstract: The purpose of this study was to determine simple and multiple relationships between leadership styles and emotional intelligence component in the Heads of Departments University of Mohaghegh Ardabili. The Statistical population involved all the academic staff members and Heads of the Departments at the university (N = 118). Based on the nature of subject and research questions, correlation method was thought to best serve the purpose of the present study. To collect the data, Emotional Intelligence Scale (EIS) and Bass and Avolio Multifactor Leadership Style Questionnaire (MLQ form 5X) were used. For data analysis, Pierson correlation and multiple regression in enter way were used. The Results indicated high satisfaction on the part of the majority of the members about the performance and leadership style of the Heads of the Departments. Also, transformational style was found to be of high prevalence among the Heads of the Departments. Furthermore, prediction of variables with the use of multivariate regression indicated that only the use of emotional subscale can predict the transformational and Laissez faire leadership styles, but the use of emotional, emotional regulation and assessment and expression of emotions (p<0.01) can predict the transactional leadership styles. In the study of the relationship between variables, it was found that a positive correlation exists between transformational leadership style and emotional intelligence (p<0.05) has negative correlation between transactional leadership style and emotional intelligence (p<0.01), but not significant relationship between Laissez faire leadership style and emotional intelligence was found. This study showed that EI and its different dimensions have a high power in predicting leadership styles of the Heads of the Departments.
