The Bormida di Spigno is a 58 km long river of north-west Italy.
The headwaters of the Bormida di Spigno are in the Ligurian province of Savona above Pian dei Corsi at 1,000 metres above sea level in a transitional zone between the Alpine and Apennine mountain ranges. There its waters run as the separate Bormidas of Mallare and Pallare in distinct close valleys before quickly joining after a few kilometers. It joins with the Bormida (or Bormida di Millesimo) near Bistagno in the Piedmontese province of Alessandria.
