The Biobío Region (Spanish: Región del Biobío [ˌbi.oˈβi.o]) is one of Chile's sixteen regions (first-order administrative divisions). With a population of 1.5 million, thus being the third most populated region in Chile, it is divided into three provinces: Arauco, Biobío and Concepción. The latter contains its capital and largest city, Concepción, a major city and metro area in the country. Los Ángeles, capital of the Biobío Province, is another important city in the region.
