Intragna is a village and locality in the municipality of Centovalli[1] in the district of Locarno of the canton of Ticino in Switzerland.

[2] During the Middle Ages the landlords over the village included both the Bishop of Como and the Capitanei (noble families) of Locarno.

In 1531, the Swiss Confederation rejected an application from Intragna, Ascona, Onsernone and Centovalli to form a municipality that was independent of Locarno.

Likewise, the conflict-ridden attempts of Golino to form an independent municipality failed in the 18th and 19th centuries.

Starting in the 16th century, the income from seasonal migration (especially chimney sweep in Lombardy and Piedmont) were added to the local economy.

Between 1631 and 1847 the people of Rasa (along with Ronco, Losone and Terre di Pedemonte) possessed the monopoly for loading operations at the Custom House of Livorno.

While the population in the higher settlements has declined sharply (Rasa: 200 inhabitants at the beginning of the 16th century, while only 11 in 1970), Intragna and Golino, due to their proximity to Locarno, have grown since 1970.

Golino, Verdasio, Pila, Vosa, Cremaso, Calezzo, Costa, Corcapolo and Rasa are fraziones of Intragna.
