Coastal tourism is one of the largest and fastest-growing sectors of the global tourism industry. Simultaneously, the concept of the Blue Economy has emerged as a holistic framework integrating sustainable use of marine resources with economic development, environmental protection, and social equity. This paper examines the convergence of Blue Economy principles with coastal tourism development, focusing on marine ecosystem preservation, community empowerment, ocean-friendly tourism design, and maritime innovation. Through conceptual models and hypothetical case studies, the research identifies strategies for balancing economic gains with ecological resilience. Results indicate that integrating Blue Economy approaches into coastal tourism enhances ecosystem stability, diversifies local economies, and improves destination competitiveness.
