. This paper explores the integration of critical thinking (CT) in English language teaching, emphasizing its vital role in both academic and professional settings. Although critical thinking is frequently highlighted in curriculum guidelines, many English language teachers find it challenging to effectively teach these skills. This study reviews various approaches to CT instruction, including general, infusion, immersion, and mixed methods, and evaluates their effectiveness in enhancing students' critical analysis and reasoning abilities. It highlights how CT is linked to language proficiency and cultural context, noting the potential resistance due to traditional teaching methods and lack of materials. The discussion includes practical strategies for fostering CT in the ESL classroom, such as Socratic questioning, genre awareness, corpus analysis, and collaborative work. Additionally, the study examines simulation/game-based approaches and content-based instruction as effective methods for embedding CT in language learning. Results indicate that the infusion and immersion approaches are particularly successful in subject-specific CT development, while the mixed approach provides a balanced methodology. The paper concludes by stressing the importance of teacher training in CT and the necessity of creating a supportive learning environment to reduce student anxiety. By fostering critical thinking, ESL educators can better prepare students to navigate complex academic and professional landscapes, ensuring their long-term success. This study underscores the need for a nuanced understanding of CT and the careful scaffolding of language to enhance students’ analytical skills.
