The 7.35×51mm Carcano is a rifle cartridge used by the Italian military during World War II.

It was designed during the 1930s to replace the 6.5×52mm Carcano used by the Italian military. Unlike the 6.5 mm, the 7.35 mm cartridge featured a Spitzer-style bullet to minimize air resistance in flight, however due logistical concerns during World War II, it never managed to replace the 6.5 mm round, which remained standard until 1945.
