This study sought to uncover the reading strategies utilized by Iranian undergraduate English Foreign Language (EFL) learners and their relationship with personality types. To this end, 194 university EFL learners were asked to fill out the Myers-Briggs Type Indicator (MBTI) to identify their personality types and answer a reading strategy questionnaire to tap into metacognitive, cognitive, and support strategies. Results obtained indicate that the participants are moderate reading strategy users. Their most frequent strategies were the cognitive strategies, followed by the metacognitive and support strategies. An interview was also conducted and findings both confirmed the data accumulated through the questionnaire, and even revealed some additional strategies which had not been previously included in the questionnaire. Among the four bipolar personality types, introversion did show a significant positive relationship with reading strategies suggesting that the learners' extraversion and introversion dichotomy should be taken into consideration to shed light on their reading strategy use.
