The current study aims at investigating EFL teachers' perceptions of critical thinking as well as the strategies they use to incorporate critical thinking into their EFL classes. Moreover, it aims at investigating the challenges that EFL teachers face when incorporating critical thinking strategies in their classrooms. The current study was conducted with twenty EFL teachers at 4 secondary schools. The findings indicate that the participating teachers have some but inadequate knowledge about critical thinking and they sometimes incorporate certain techniques to cultivate critical thinking among language learners. It is recommended that there should be more focus on exploring critical thinking conceptions and practices among EFL teachers working at different levels.
