Abstract: Listening anxiety has a detrimental effect on language learners. In the Iranian EFL context listening comprehension remains as one of the most problematic skills for learners. To figure out learners’ sources of listening comprehension anxiety and the factors that might reduce listening anxiety, the semi-structured interviews were conducted with fifteen participants. Through qualitative analysis several factors were identified as having influence on Iranian EFL learners’ listening anxiety. These factors were divided into three categories, i.e. individual factors (nerves and emotionality, using inappropriate strategies and lack of practice), input factors (lack of time to process, lack of visual support, nature of speech and level of difficulty) and environmental factors (instructors, peers and class environment).
