Urban biodiversity continues to decline under rapid urbanization. Although biophilic design and green–blue infrastructure have strengthened nature integration into cities, planning and design practice often prioritizes human-centered service delivery and overlooks process-led recovery. Rewilding addresses this gap by foregrounding ecological autonomy, succession, and trophic complexity, yet its urban translation remains limited. This review therefore examined how rewilding could be operationalized as a design-oriented strategy in cities. An evidence-to-design roadmap was proposed to link rewilding logics, biodiversity aims, and urban planning and design, with a dual-level protocol adopted: 1) a macro-level scientometric overview of 1184 records (1990–2025) to locate urban rewilding studies within the broader literature; and 2) a micro-level PRISMA-guided synthesis of 103 spatially explicit studies coded by rewilding pathway (active/passive), targets, spatial and temporal scales, data, methods, and spatial variables. Macro mapping indicated that urban-related studies were late-emerging and weakly consolidated. Micro synthesis revealed pathway differences: passive studies primarily traced vegetation and landscape trajectories, while active studies employed suitability and connectivity modeling for intervention screening. Urban studies remained scarce (N = 9), with passive studies dominant and connectivity analyses particularly common, focusing on vegetation, birds, and planning-oriented targets. Building on these patterns, this study derived a four-level framework comprising design intent, strategic planning, tactical methodology, and operational application, translating rewilding into staged, scalable decisions aligned with urban planning and design workflows. This review positioned rewilding as a process-centered complement to conventional landscape design approaches, offering an actionable pathway for embedding biodiversity regeneration within urban systems.
