<jats:title>Abstract</jats:title> <jats:p>This entry explores the relevance and applicability of User Experience (UX) design principles in the context of Computer‐Assisted Language Learning (CALL). UX, a discipline originating in human–computer interaction, focuses on optimizing user behavior, perception, and engagement across digital and physical environments. While it shares commonalities with related fields such as instructional design (ID), universal design for learning (UDL), and learning experience design (LXD), UX is distinct in its emphasis on shaping learner behaviors through iterative, user‐centered design. The entry outlines how core UX concepts such as user‐centricity, predictability, and structure, and UX methods such as usability testing and card sorting, can inform CALL research and materials development. We discuss how UX approaches can complement existing methods, provide insights into learners' moment‐by‐moment experiences, and guide the design of more intuitive, effective, and motivating learning tools. Recognizing the constraints of educational settings, we also present strategies to overcome barriers to implementing UX design in various language‐learning settings where resources may be limited. Ultimately, we argue that UX design offers a flexible, learner‐focused complement to established educational design frameworks, enabling researchers, teachers, and materials designers to better meet the evolving needs and behaviors of language learners in digital environments.</jats:p>
