The present research is of a comparative causal type and its purpose is to investigate the effect of religious attitude and emotional intelligence on the aggression of professional wrestlers. Data related to religious attitude, emotional intelligence and the effect of these two on aggression were collected from 100 wrestlers using religious attitude questionnaires, Shott's emotional intelligence questionnaire and Nelson's anger questionnaire. The results of the research showed that religious attitude and emotional intelligence have an interactive effect on reducing the aggressiveness of professional wrestlers. Based on the subjects' statements, the results showed that aggression among people with high religious attitude was lower than among people with low and medium religious attitude. The results of two-variable variance analysis also showed that the interactive effect of the two components of religious attitude and emotional intelligence on aggression is statistically significant, in other words, religious attitude and emotional intelligence have an interactive effect on the aggression component of professional wrestlers.
