The Cannone-Mitragliera da 37/54 (Breda) was a 37 mm (1.5 in) automatic anti-aircraft gun produced by the Breda company in Italy.

It was used by both the Regia Marina and the Regio Esercito during World War II, with the former using it as the standard light anti-aircraft weapon on its battleships and cruisers. Nazi Germany used captured weapons after the surrender of Italy in 1943 as the 3.7 cm Breda (i).
