Borgnone is a hamlet part of the municipality of Centovalli in the district of Locarno in the canton of Ticino in Switzerland. Not to be confused with much bigger Camedo or with Lionza or Costa.

Borgnone is first mentioned in 1364 as Brugnono. In the Middle Ages it was part of the Locarno region. In the 15th century, it became a Degagna, which was part of the bailiwick of Locarno between the 16th century and 1798. It then became an independent political municipality when the municipality of Centovalli was split in 1838.
