Tricontinental Chile is a geopolitical concept denoting Chile's unique position with its mainland in South America, Easter Island in Oceania (Polynesia) and the Chilean Antarctic Territory in Antarctica.

The Boundary Treaty of 1881 between Argentina and Chile was signed on 23 July 1881 in Buenos Aires by Bernardo de Irigoyen, for Argentina, and Francisco de Borja Echeverría, for Chile, with the aim of establishing a precise border between the two countries based on the uti possidetis juris principle. Despite dividing largely unexplored lands, the treaty laid the groundwork for nearly all of Chile's and Argentina's 5600 km current border.
The southern coast of Chile presents a large number of fjords and fjord-like channels from the latitudes of Cape Horn to Reloncaví Estuary. Some fjords and channels are important navigable channels providing access to ports like Punta Arenas, Puerto Chacabuco and Puerto Natales.
