Concepción (Spanish pronunciation: [kon.sepˈsjon] (listen); originally: Concepción de la Madre Santísima de la Luz, "Conception of the Blessed Mother of Light") is a city and commune in central Chile, and the geographical and demographic core of the Greater Concepción metropolitan area, one of the three major conurbations in the country. It has a significant impact on domestic trade being part of the most heavily industrialized region in the country. It is the seat of the Concepción Province and capital of the Bío Bío Region. It sits about 500 km south of the nation's capital, Santiago.
The city was first settled in the Bay of Concepción, in the zone that would later become the commune of Penco, now part of the Concepción conurbation. The city's demonym, penquista, comes from the place of its original foundation.
