Background: This scoping review aimed to identify and synthesize the evidence on mindfulness-based interventions targeting mental health outcomes in working adults. Methods: A comprehensive search was conducted in four electronic databases (PubMed, Scopus, Web of Science, and OTseeker) up to October 2025. The review followed PRISMA-ScR guidelines. Methodological quality was evaluated using the Oxford Centre for Evidence-Based Medicine (OCEBM) classification. The protocol was prospectively registered on the Open Science Framework (OSF). Results: A total of 1803 records were identified, of which nine randomized controlled trials met the inclusion criteria. The included studies examined Mindfulness-Based Stress Reduction, Mindfulness-Based Self-Care, Mindfulness-Oriented Therapy, and digital mindfulness interventions. Overall, mindfulness interventions demonstrated beneficial effects across several mental health domains. Conclusions: Mindfulness-based interventions show promising benefits for improving mental health among working adults. Their structured, brief, and adaptable formats support their feasibility for integration into occupational health programs and workplace mental health promotion.
