Puente Alto is a major commune and city in the southern sector of the Santiago Metropolitan Region of Chile, serving as the capital of Cordillera Province, Chile. Located on the eastern margin of the Maipo River basin and at the foot of the Andes, it is one of the most populous urban areas in the country and an important node in the Greater Santiago metropolitan network. Historically a rural outpost that urbanized rapidly in the 20th century, the city connects to central Santiago via transport corridors and interfaces with neighboring communes such as La Florida, San José de Maipo, and Pirque.
The territory around Puente Alto was inhabited by indigenous groups prior to Spanish colonial settlement during the era of the Captaincy General of Chile. During the colonial and republican periods landholdings operated as estancias linked to families also present in the histories of Santiago, Chile and Valparaíso. The name emerged in the late 19th century coinciding with railroad expansion related to the Ferrocarril del Sur and agricultural development tied to the Maipo Valley irrigation projects. The commune was officially established in 1898 amid administrative reforms of the Republic of Chile. Throughout the 20th century growth accelerated with suburbanization, the influence of industrialization in Greater Santiago, and migration waves associated with national events such as the agrarian reforms of the Presidency of Salvador Allende and the urban policies of the Military dictatorship of Chile (1973–1990). Urban consolidation continued under democratic administrations including those of Patricio Aylwin and Michelle Bachelet, with transport investments like Santiago Metro expansions shaping modern residential patterns.
Puente Alto occupies a transitional landscape between the Mapocho River watershed to the north and the Maipo watershed to the west, sitting at the pre-Andean piedmont near hills such as Cerro Chena and Cerro Manquehue. The climate is Mediterranean, influenced by orographic effects from the Andes and seasonal shifts of the South Pacific High. Vegetation remnants include sclerophyllous scrub and planted eucalyptus groves associated with forestry initiatives linked to companies like Forestal Mininco and reforestation efforts promoted by the Ministry of Agriculture (Chile). Environmental challenges include urban sprawl, air pollution episodes driven by the Metropolitan Region of Santiago inversion layer, flood risks associated with the Maipo River and sediment dynamics influenced by mining and hydropower projects in upstream basins such as those around Maule Region and El Teniente. Conservation and green-space programs interact with national bodies like the National Forestry Corporation (Chile) and regional authorities in the Santiago Metropolitan Region.

Age distribution trends reflect a significant working-age population, with impacts on commuting flows to employment centers in Santiago, Chile and educational enrollment at institutions including campuses of the Universidad de Chile, Universidad de Santiago de Chile, and regional technical institutes such as INACAP.
