Bognanco, population c.250, is a commune in the Province of Verbano-Cusio-Ossola in the Italian region Piedmont, located in an Alpine valley about 120 km northeast of Turin immediately to the west of Domodossola and on the border with Switzerland. Its municipal boundaries extend over an area of 58.1 km² which ranges in altitude from 380 to 2,713 metres above sea-level and borders on the Italian communes of Antrona Schieranco, Crevoladossola, Domodossola, Montescheno and Trasquera, and Zwischbergen in the Swiss canton Valais.
