The Diego Ramírez Islands (Spanish: Islas Diego Ramírez) are a small group of lesser islands located in the southernmost extreme of Chile about 100 km (62 mi) south-west of Cape Horn and 93 km (58 mi) south-south-east of Ildefonso Islands, stretching 8 km (5 mi) north-south (not to be confused with Ramirez Island far to the north). Their land area is little more than 1 km2 (0.39 sq mi).
The islands belong to the Commune of Cabo de Hornos in Antártica Chilena Province of Magallanes y Antártica Chilena Region. They are divided into a smaller northern group with six islets, and a larger southern group, separated by a passage 3 km (1.9 mi) wide. The two largest islands, Isla Bartolomé and Isla Gonzalo, both lie in the southern group. The islands contain the southernmost point of the South American continent (including islands), a title often incorrectly awarded to Cape Horn. Águila Islet (Islote Águila), the southernmost land of the group, is at 56°32'9"S.
The Chilean Navy established a meteorological station above Caleta Condell, a small cove on the northeast side of Isla Gonzalo (Gonzalo Island), in 1957, and resupply it several times each year. This is the southernmost human-occupied outpost of South America (including islands), even if the South Sandwich Islands are regarded as part of South America, since the Argentinian station on Thule Island was dismantled in June 1982 (in the aftermath of the Falklands War). The next southerly human-occupied outpost of South America is the lighthouse of Cape Horn. Cruise ships occasionally pass by on their way to and from Antarctica.
