Key Facts

Antofagasta is a region located in northern Chile, serving as one of the country's 16 administrative regions. It occupies a strategic position along Chile's Pacific coastline, stretching from the border with Peru in the north to the Atacama Region in the south, covering approximately 126,049 square kilometers of diverse terrain that includes coastal areas, the world's driest desert, and portions of the Andes Mountains. With a population of around 607,000 people, Antofagasta is one of Chile's most sparsely populated regions despite its economic significance. The region is administratively divided into four provinces: Antofagasta, El Loa, Tocopilla, and the recently created Litoral province. Known as Chile's mining heartland, Antofagasta contains some of the world's largest copper mines and contributes significantly to Chile's position as the global leader in copper production. The region's capital city, also named Antofagasta, serves as a major port and urban center, while other important settlements include Calama, San Pedro de Atacama, and Tocopilla.
