It has a population of 2,874, including both naval personnel and civilians. Puerto Williams is in some contexts referred to as the world's southernmost city.
The settlement was named after John Williams Wilson, who founded Fuerte Bulnes, the first settlement in the Strait of Magellan since 1587. Puerto Luisa was its original name. Since its foundation in 1953 the settlement has served primarily as a naval base. But recently navy personnel living in Puerto Williams have decreased while civil population has increased.

Puerto Navarino, on the west side of the Navarino island, was founded in June 1938. Puerto Williams itself was founded 1953 and its naval hospital was inaugurated in 1960 with 463 m2 (today 638 m2). In 2002 the electrical power supply was transferred from the Chilean Navy to a private provide.
