This study aimed to investigate the relationship between Iranian EFL learners' interpersonal and intrapersonal intelligence and their speaking ability. To achieve this aim, 30 Iranian EFL learners whose level of proficiency was intermediate participated in this study. The participants' general English knowledge was measured via Oxford Quick Placement Test (OQPT). The placement test revealed that all participants were intermediate learners and homogenous. The other instruments of the study were the Multiple Intelligences Inventory and the speaking test. After evaluating the participants' general English knowledge, the speaking test was given to them. After collecting the speaking tests' results, the questionnaire was distributed among the participants, and they were requested to answer all the items in it carefully and honestly. The Pearson correlation coefficient test was used to show the relationship between the participants' interpersonal and intrapersonal intelligence and speaking skill. The findings revealed positive and significant relationships between the participants' interpersonal and intrapersonal intelligence and their speaking. The findings of the study would be useful for teaching and learning speaking skill and researchers in the fields of TEFL and sociolinguistics.
