Borgnone is a hamlet part of the municipality of Centovalli in the district of Locarno in the canton of Ticino in Switzerland.

The Church of Beata Vergine dell 'Assunta (built 1364–65) underwent several transformations.

A strong seasonal emigration supplemented the income from agriculture and animal husbandry of the residents.

The majority of the population (1990: 70%) is in the services sector, and half of all residences are second or vacation homes.

[3] Borgnone is located in the Locarno district, on the northern slope of the Centovalli at an elevation of 713 m (2,339 ft).
