This study aimed to investigate the factors that influence boredom in English as a Foreign Language (EFL) classroom at University of Zawia, and its impact on students ' comprehension and academic performance among second –semester students at the IT College. Data were collected using a mixed- methods research design by using an open ended questionnaire completed by 121 participants and semi -structured interviews conducted with 8 English teachers. The findings revealed that boredom was mainly associated with traditional teaching, teacher-centered methods, lack of instructional variety, and limited classroom interaction, with students' limited background knowledge may also contribute to disengagement. The results further indicate that boredom negatively influences students' concentration, comprehension, participation, and overall academic performance. However, teachers pointed out that integrating technology and interactive activities, connecting lessons to real-life contexts, simplifying explanations, and providing positive feedback can effectively reduce boredom and enhance engagement. The study ends with a discussion of the implications of the results and provides suggestions for further research.............. Keywords:...............
