<p>Foster youth often experience complex trauma, instability, and systematic inequities that contribute to long-term mental health challenges. This conceptual review synthesizes evidence from randomized controlled trials, systematic reviews, and applied practice to examine how Mindfulness-Based Interventions (MBIs) can support trauma recovery among foster youth. Drawing from recent Randomized Controlled Trials (RCTs) and applied practice, this conceptual review synthesizes evidence showing that MBIs reduce Post-Traumatic Stress Disorder (PTSD) symptoms, improve emotional regulation, and strengthen relational trust. The paper highlights the need for culturally responsive adaptations that align mindfulness practices with the lived experiences and values of racially and ethnically diverse foster youth. Evidence from school-based, digital, and community programs demonstrates that integrating mindfulness into child welfare and educational systems can promote self-awareness, empowerment, and psychological well-being. Attention is given to long-term outcomes, including the potential for sustained improvements in self-concept, coping, and relational functioning. The article concludes with implementation strategies and policy directions to embed trauma-informed, culturally grounded MBIs within foster care settings. By investing in training, community engagement, and longitudinal research, stakeholders can strengthen resilience and promote healing for youth with histories of trauma.</p>
