The Strona is a mountain torrent in the Province of Verbano Cusio Ossola, northern Italy, a tribitury of the Toce. It rises on Monte Capezzone at an elevation of 2,421 m and runs through the Valle Strona (the communes of Valstrona, Massiola, Quarna Sopra, Loreglia, Germagno, Omegna, Casale Corte Cerro and Gravellona Toce) before entering the Toce. At Omegna it is joined by the Nigoglia, the outlet of Lago d’Orta.
