Chile's former Tarapacá region was a former Peruvian province, which was occupied by Chile under the 1883 Treaty of Ancón at the close of the War of the Pacific, and then formally annexed in 1929 by the Treaty of Lima.



The Arica and Parinacota borders Peru to the north, Bolivia to the east and Chile's Tarapacá region to the south.[4]

The region is within the Norte Grande (Far North) natural region. It combines deserts, green valleys, the steep and volcanic Andes mountains, and the Altiplano (high plain) to the east. A narrow coastal strip of low-lying land no more than 2 kilometres (1 mi) wide separates the Pacific's Nazca plate from the Andes. Its Parinacota volcano is the region's highest elevation at 6,348 metres (20,827 ft) and is on the northern border with Bolivia in Lauca National Park.

The two main rivers of the region are the Lauca, which flows into the Coipasa lake in Bolivia, and the Lluta, which flows into the Pacific Ocean. Lake Chungará at 4,517 metres (14,820 ft) above sea level ranks as one of the highest in the world



As of 2015, there were (estimated) 239,126 persons living in the region,[5] for a population density of 14.2 inhabitants/km².

The largest city in the region is Arica, with 210,936 inhabitants.[source?]

In 2007, the region was subdivided to create the Arica y Parinacota region and the present day Tarapacá Region to the south. The region is further subdivided into two provinces: Arica and Parinacota.
