The Alta Valle Antrona Natural Park is a nature reserve in Piedmont, in Italy.

It is in the Ossola valley between an altitude of 500 and 3.656 m (Pizzo d'Andolla).

Despite the mining activities carried out in the past, the natural vegetation and fauna have been preserved.

A great portion of the park adjoins Switzerland.
