The present chapter deals with Teaching English as a Foreign Language (TEFL) postgraduate students’ perception of critical thinking (CT) in learning English as a foreign language. It starts with various definitions of the concept, especially from the two known perspectives on CT, considering CT as a cognitive skill and regarding it as a disposition. The chapter then continues with the relation- ship between CT and foreign language learning, which is followed by a section entitled “Why focus on CT?”. Next, the empirical section of the study presents and discusses TEFL postgraduate students’ conceptualizations of CT and their perceptions of the obstacles to their CT development, as well as their suggestions on how to improve CT skills. The chapter ends with concluding remarks and presents some implications on how to enhance CT skills.
