Critical thinking is integral to English language teaching (ELT) as it enhances both linguistic competence and higher- order cognitive abilities such as analysis, evaluation, and problem-solving. This paper explores how critical thinking can be systematically embedded in ELT to foster intellectual maturity and independent learning. It examines pedagogical strategies-including Socratic questioning, debates, case studies, and problem-based learning-that stimulate discussion, challenge assumptions, and encourage evidence-based reasoning. These approaches not only strengthen students' speaking, listening, and writing skills but also cultivate skills in argumentation, bias recognition, and decision- making. The study highlights the role of collaborative and discussion-based learning environments in deepening engagement and building students' confidence to express well-reasoned views. Findings indicate that integrating critical thinking into ELT improves language proficiency while equipping learners to navigate complex situations, manage diverse perspectives, and respond thoughtfully to real-world challenges. Ultimately, embedding critical thinking in language classrooms prepares students to be analytical, solution-oriented, and reflective individuals capable of meaningful contributions in a dynamic global context.
