Sport is more than just an activity that develops an individual's physical capacity; it is a significant social phenomenon that affects human life in multifaceted ways through its psychological, social, and cultural dimensions. Individuals who are introduced to sports, particularly during childhood and adolescence, are seen to develop healthy habits that last a lifetime and become more socially integrated individuals. In this context, taekwondo, a martial art, stands out with its philosophical foundations and disciplinary approach. Taekwondo is a sport that focuses on values ​​such as mental resilience, self-control, respect, and responsibility, in addition to physical development. Numerous academic studies have shown that it has significant effects on social adaptation, self-confidence development, and psychological resilience, especially in children and young people. This book chapter examines the social and psychological effects of taekwondo on children and individuals from a holistic perspective.
