Peru is organized into 25 primary administrative regions plus the distinct Lima Province, which contains the national capital. These regions serve as the top subnational units for planning, public investment and coordination of services; further subdivisions include provinces and districts (Provinces of Peru). For a general reference to the modern regional division see administrative regions of Peru. Regions of Peru

Regional governments combine an elected executive and a regional council and are responsible for regional development plans, some social services and coordination with central government agencies. Over recent decades Peru pursued a process of decentralization that strengthened regional authorities and sought to improve local management of economic and environmental resources. The precise powers and organization of regional governments are defined by national law and can vary in practice according to capacity and local arrangements.

Peru's regions encompass very different environments and economic bases. The coastal regions are centers of agriculture, manufacturing and ports (for example Piura, Ica and Arequipa). The Andean highlands include major mining, farming and cultural centers (for example Cusco, Puno and Ancash). The Amazonian regions are less densely populated and emphasize forestry, biodiversity and river transport (Loreto, Madre de Dios and Ucayali). Many regions are noted for archaeological sites, native cultural traditions and tourism; for instance, the city of Cusco serves as a gateway to historical attractions.

Region-level planning matters for infrastructure, education, health and economic promotion. Regional authorities work with provincial and district governments to administer public works, agricultural programs, and environmental protection. Some areas — such as the constitutional province and major port of Callao — have special administrative status linked to their strategic functions. The distinction between the Lima Region and the Lima Province is an example of how political geography in Peru can reflect urban concentration and national governance needs.

Understanding the regions is useful for travel planning, study of economic geography, and engagement with public policy. Each region combines historic identity, environmental characteristics and administrative functions that shape daily life and long-term development in Peru.
