Ronco di Maglio is a mountain in Liguria, northern Italy, part of the Ligurian Prealps.

The mountain is located near the centre of the Provincia di Savona, between the comuni (municipalities) of Osiglia and Bormida, and is one of the highest of the Ligurian Prealps.

Going South a saddle at 858 metes divides it from Bric della Croce (911 m), while northwards the ridge lowers and ends up between Plodio and Millesimo.

[3] Ronco di Maglio can be ascended by various waymarked foothpats; among them can be reminded the one starting from Colla Baltera (794 m[1]) which, passing through Bric della Croce, reaches the summit from South.

The mountain and its surrounding area are part of a SIC (Site of Community Importance) called Ronco di Maglio (code: IT1322216).
