Caleta Coloso is a small Chilean coastal village located approximately 15 kilometers south of Antofagasta, accessible via Avenida Jaime Guzmán, also known as Ruta 1. The settlement sits near Quebrada De Jorgillo along the Pacific coast.

The area is home to both an artisanal fishing community and Puerto Coloso, a port facility owned by Minera Escondida.

In the early 2000s, the port infrastructure underwent significant renovation, including construction of a new pier for artisanal fishermen, a rock breakwater, and improved road access to the Minera Escondida port terminal.
