ABSTRACT Solar‐driven interfacial evaporation (SDIE) has emerged as a promising strategy to alleviate the global freshwater crisis owing to its high efficiency, low energy demand, and environmental compatibility. Natural and bio‐inspired materials offer unique structural and functional advantages in this context, enabling enhanced solar absorption, efficient water transport, localized thermal management, and effective salt resistance. Despite these advances, challenges such as limited material durability, incomplete structural integration, and inefficient vapor condensation continue to restrict long‐term stability and large‐scale deployment. Looking forward, progress in multifunctional material systems, rational structural design, and integrated water collection strategies inspired by biological prototypes will be essential. This review provides a comprehensive and forward‐looking perspective on advancing SDIE by coupling biological inspiration with functional engineering, highlighting pathways toward multifunctional, integrated, and sustainable solar evaporators.
