The purpose of this study is to investigate the English reading strategies of Korean secondary EFL learners by their personality types. The study was conducted with 112 middle school students and 100 high school students in Korea. The instrument used for personality measurement was the MBTI test. A reading strategy questionnaire was used to see how frequently each reading strategy was used while students read passages in English. The collected data was analyzed using t-test and two-way ANOVA to see the differences between high school and middle school students in terms of personality types. The results of the study demonstrated that there were significant differences in strategies used by the two groups of students and high school students used more reading strategies than middle school students. It was also found that the students exhibited some differences in reading strategy use depending on their personality types, especially between the N(Intuition) and S(Sensing) types. For example, students with N(Intuition) types used more vocabulary-comprehension, guessing, and metacogntive strategies than S(Sensing) types. Pedagogical implications and suggestions for classroom English teachers are discussed based on the results of the current study.
