This study investigated the interrelationships among EFL learners' self-efficacy, autonomy and listening comprehension ability. Ninety female learners of intermediate level participated in the study. They were between 16 and 24 years old. In order to obtain the required data on the three variables (i.e., self-efficacy, autonomy, and listening comprehension ability), the researchers, after administering a standard language proficiency test to ensure the participants' homogeneity, used Listening Self-efficacy Beliefs Questionnaire, Listening Autonomy Questionnaire, and Listening Proficiency Test, respectively. First, the participants were asked to complete the two self-report scales, after which they were given a listening comprehension test to attain their listening comprehension ability. The data were analyzed using three Pearson's Product-moment correlation coefficients to assess the relationships among the research variables. The findings revealed that there was a positive correlation among Iranian EFL learners' listening self-efficacy beliefs, listening autonomy, and listening comprehension ability. Accordingly, it is suggested that building self-efficacy and autonomy in listening comprehension is crucial to ensure the success of EFL learners in listening comprehension.
