This study investigated the relationship between five teaching styles and emotional intelligence among 102 Iranian English instructors from different universities in Tehran, Iran. To this end, the data were obtained through two phases of quantitative and qualitative data collection. To achieve quantitative data, the participants were asked to fill in two questionnaires, including the Teaching Styles Inventory (version 3.0) and the Emotional Intelligence Scale. The second phase of data collection was performed through collecting qualitative data by conducting a semi-structured interview on 10 English instructors. To analyze quantitative data, multiple regression analyses were run. Likewise, the qualitative data was analyzed through data reduction process in order to realize the instructors’ attitudes toward the different aspects of teaching styles and to find out to what extent their attitudes were similar to one another. The results demonstrated that among various teaching styles, including expert, formal authority, personal model, facilitator, and delegator, merely the delegator style had statistically significant association with emotional intelligence. Furthermore, the relationship between personal model style and emotional intelligence was considerable, though not statistically significant. The findings and their implications are fully discussed.
