Fiocchi Munizioni (Fiocchi Ammunition) is one of Italy's largest and oldest manufacturers of ammunition. The company's headquarters and main production plant are in Via Santa Barbara in Lecco, Italy.

Fiocchi Munizioni was founded on 3 July 1876 in Lecco, Italy, by accountant Giulio Fiocchi.

In 1876, Giulio Fiocchi took over the ammunition production part of a weapon and ammunition company already based in Lecco, which produced small-caliber ammunition.

At that time a radical change was introduced in firearms: the newly developed breech-loader replaced the traditional muzzle loader. Fiocchi started manufacturing cases with primers suitable for reloading; in the early 1890s production was extended to complete cartridges loaded with bullets or shot. At the same time, Fiocchi gave up the production of black powder, as it was no longer profitable.

At the beginning of the 20th century, Fiocchi diversified and began making snap fasteners using scraps from cartridge production. Fiocchi Snaps was formed in 1903. It assumed an important role to counterbalance the trend of the ammunition market, but at the end of the 1980s Fiocchi made a decision to focus on ammunition as its core business, and the snaps factory was sold.

During its long life, Fiocchi has manufactured all kinds of ammunition from pinfire, shotshells, and cartridges to all kinds of cartridges and cases, both rimfire and centrefire. They are known for manufacturing rarer cartridges for collectors and enthusiasts, for example the .455 Webley.
