Port Aguirre, Fishing port in Aysén Region, Chile.

Puerto Aguirre lies on the south shore of Las Huichas Island, on the Ferronave Channel next to the Moraleda Channel, between the mouth of the Aysén Fjord and the Puyuhuapi Channel. Together with Estero Copa and Caleta Andrade, immediately to its east, it forms a small conurbation of about 1,850 people (2012 estimate). The town has a gym, a cultural centre, two schools, a football pitch, a Carabineros post, a Navy port captaincy and a local radio station.

The settlement grew from a camp of Chilote loggers cutting Guaitecas cypress and later smoking cholga mussels, who arrived in the early 20th century and first called it Puerto Huichas. A maritime mayoralty installed under President Pedro Aguirre Cerda, whose name the town now bears, is counted as its founding; the first school followed in 1942. Mussel canneries opened at Caleta Andrade in 1946 and Estero Copa, and in 1978 the region's first fish and shellfish freezing plant was installed here.

The residents have deep roots in Chiloe maritime traditions and work mainly in fishing and aquaculture. These activities shape daily life and are visible throughout the village.

Visitors should bring Chilean pesos and necessary supplies from larger cities, as the village has limited shops and card payments are not always accepted. Cash is more practical than other payment methods in this remote location.

Ferries between Puerto Montt and Puerto Aysén call at the village as an intermediate stop. Francisco Coloane, in the 1960s, recalled that the only woman he saw working as a diver in Chile was in Puerto Aguirre.
