The present study aimed at investigating the relationship between interpersonal intelligence of Iranian bilingual and multilingual EFL learners and their reading comprehension achievement. To do so, 60 intermediate EFL students were selected from a group of 80 based on their OPT scores. They were non-randomly divided into two experimental groups. Data collection took place during the summer semester 2017. Once the interpersonal intelligence questionnaire and the reading comprehension test scores had successfully been collected, the results of Pearson product correlation coefficient analyses showed that there was a significant relationship between Iranian bilingual and multilingual EFL learners’ interpersonal intelligence and their reading comprehension achievement: higher interpersonal intelligence was associated with higher levels of reading comprehension achievement and higher statistical significance among bilingual learners. Therefore, it was suggested that Multiple Intelligence Theories could still serve as determining factors in planning programs to teach reading in spite of the theoretical, conceptual, and empirical criticisms of the idea.
