Paposo or Caleta Paposo is a hamlet in the southern part of Antofagasta Province, Chile. It is located on a narrow coastal plain bordering the Pacific Ocean. The census of 2002 counted 259 inhabitants, who predominantly relied on fishing and mining for a living. Paposo has a desert climate, but "fog oases" exist on mountain slopes near the sea. In a region almost devoid of vegetation, these oases, also called lomas, support a variety of flora found from about 1 km to 4 km inland.
