The II Antofagasta Region (Spanish: II Región de Antofagasta) is one of Chile's fifteen first-order administrative divisions. It comprises three provinces, Antofagasta, El Loa and Tocopilla. It is bordered to the north by Tarapacá and by Atacama to the south and is the second-largest region of Chile. To the east it borders with Bolivia and Argentina. The capital of the region is the port city of Antofagasta, another important city is Calama. The main economic activity is copper mining from the giant porphyry copper systems located inland.
Climate is extremely arid albeit somewhat milder near the coast. Nearly all of the region is devoid of vegetation except at close Loa River or oasis like San Pedro de Atacama. Much of the inland is covered by salt flats, tephra and lava flows. The coast exhibits prominent cliffs.
The region was sparsely populated by indigenous Changos and Atacameños until massive Chilean immigration in conjunction with a saltpeter boom in the later 19th century. The region used to be Bolivian until the War of the Pacific broke out in 1879.
Antofagasta's history is divided, as the territory, in two sections, the coastal region and the highlands plateau or altiplano around the Andes. In pre-Columbian times, the coastline was populated by nomadic fishing clans of Changos Indians, of which very little is known, due to very limited contact with the Spanish conquerors.
The inland section was populated by the Atacaman culture around the great dry salt lake called Salar de Atacama, the Loa River basin and valleys and oasis across the altiplano, with the most important settlement being the village of San Pedro de Atacama.
The Atacaman culture was deeply influenced by Tiwanaku culture and later fell under Inca rule. Atacamans' harvested mainly corn and beans and developed trade as far as the Amazon basin and Pacific shores. The arrival of the Spaniards in the 16th century did not destroy the culture but transformed it deeply through the process of mestizaje, in which both cultures mixed. Under the Spanish rule, Atacaman territory (only the inlands), was placed under the administration of Charcas Audience and at the time of independence general Simón Bolívar integrated (both inland and coast regions) into the new Republic of Bolivia, under the name of "Litoral". This decision was disputed by the Chilean Government and has been a source of conflict until present times. Chile claimed that according to the Uti possidetis of the Spanish crown, the coastal region belong to them and their territory bordered directly with Peru.
Chileans explorers such as Juan López and José Santos Ossa discovered rich nitrate and guano deposits which produced a massive Chilean colonization of the coastline. Friction between the new settlers from both countries grew until 1879 when the War of the Pacific erupted. Antofagasta was permanently annexed by the Chilean government at the end of the war.
Colonization by Chileans followed mainly from the "Little North" (the contemporary regions of Atacama and Coquimbo, also known as the III and IV regions), into the new territories of Antofagasta and Tarapacá, nicknamed the Norte Grande or "the Great North".
In the early 20th century the region became a significant base of Chile's union-organizing movements. It continued to depend economically on the nitrate-extraction industry until its replacement by copper mining. Two of the largest and richest open pit mines in the world are located in Antofagasta: La Escondida and Chuquicamata.
Each province in the region is further subdivided into communes.

The main river is the Loa.
The average rainfall in the Antofagasta is just 1 millimetre (0.04 in) per year. From the coast, east to the Chilean Coast Range, is the south-central part of the Atacama Desert, the driest desert in the world. Further to the east, it is part of the less arid Central Andean dry puna ecoregion. The surroundings of abandoned Yungay town have been named the driest place in the world.
In the late 19th and early 20th centuries, immigrant settlers also arrived from Europe (mainly Croatians, Italians, Spaniards, Greeks, English, French and Portuguese peoples), from Arab countries such as Lebanon and Syria, and plus smaller numbers from China, Japan, Korea, Peru and Bolivia. Various immigration flows joined with the culture of the altiplano region creating the modern culture of the north of Chile, which arguably presents more Andean- and multi-European-features than the Central Valley and mainstream Chilean culture.
The Antofagasta Region is the heart of the mining industry, Chile’s main source of export revenue. It represents 53% of Chile’s mining output, led by copper and followed by potassium nitrate, gold, iodine, and lithium. The mining industry accounts for 93.7% of the region’s exports.
Fishing and manufacturing also contribute to the income of the area.
The availability of infrastructure and services, due to the region’s mining boom, together with its abundance of beautiful natural scenery, have opened vast prospects for the travel industry, both in the interior and on the coast. Interesting tourist attractions include the small town of San Pedro de Atacama, once the center of the Atacameño culture, Atacama Salt Flat, the Valley of the Moon, the Quitor Pukará, the Puritama hot springs and the numerous astronomical observatories including the Very Large Telescope.
