Contemporary health challenges, such as climate change, zoonotic diseases, and growing social inequities, demand integrative frameworks that connect human and planetary well-being. This communication explores the convergence between One Health and Person-Centred Practice (PCP), highlighting how their complementary perspectives can enrich both conceptual and practical approaches to health. One Health underscores the interdependence of human, animal, and environmental health, while PCP emphasises dignity, relationships, and the care experiences of individuals. Through conceptual analysis, key areas of overlap are identified. Both paradigms share commitments to relational ethics, environmental and contextual awareness, and collaboration. One Health advances ecological and systemic determinants of health, while PCP offers structured insights into personhood, care relationships, and enabling environments. Their convergence opens possibilities for transdisciplinary education, integrated policymaking, and innovations in clinical practice that attend simultaneously to personal and ecological well-being. Case examples illustrate partial but fragmented integration, such as zoonotic disease surveillance initiatives that combine ecological and community engagement, and long-term care models that connect person-centred values with environmental design. However, systematic operational bridges between the two paradigms remain underdeveloped. Real integration requires participatory research agendas, inclusive policymaking, and educational reforms that prepare professionals with ecological literacy, ethical depth, and relational competence. In this presentation, we will examine the conceptual and practical intersections between One Health and PCP, illustrate points of convergence and fragmentation through case examples, and discuss how integrating these paradigms can support resilient, just, and compassionate health systems that care for both people and the planet.
