Cugnasco is a village in the municipality Cugnasco-Gerra of the district of Locarno in the canton of Ticino in Switzerland.

Cugnasco was an independent municipality until January 1, 2009, when it merged with Gerra (Verzasca) to form Cugnasco-Gerra.

It includes the settlements of Boscioredo, Cugnasco, Bosco, Massarescio, Medoscio, Moncucco, Pianrestello and Sciarana.

The present village developed mainly due to the herders who brought their cattle down into the Magadino valley for the winter.

Both the chapel of San Martino in Ditto and the SS Cristoforo e Anna in Curogna date from the 14th and 15th Century and contains frescoes from various periods.
