This study is a descriptive survey that investigated the relationship between emotional intelligence and conflict resolution repertoire of couples in tertiary institutions. A sample of 250 married people were drawn from the population of couples in tertiary institutions in Imo State. Two researcher made and validated instruments were used in collecting data for the study. They are: Couples' Conflict Resolution Repertoire (CCRR) and Emotional Intelligence Scale for Couples (EISC). One research question was formulated to guide the study. One hypothesis was raised and tested at 0.05 level of significance. Mean, standard deviation and Pearson product moment correlation were the statistical tools employed in analyzing the data collected. The result of the analysis indicated a significant relationship between emotional intelligence and couples' conflict resolution repertoire. Finally, it was recommended that couples should be given training on emotional intelligence skills as well as conflict resolution skills during their marriage preparatory classes prior to their wedding. Counsellors in tertiary institutions should occasionally organize seminars and workshops on emotional intelligence and conflict resolution skills for their married staff.
