The '''Otobreda 76 mm''' gun is a naval artillery piece built by the [[Italy|Italian]] [[Defense contractor|defence]] [[Conglomerate (company)|conglomerate]] of [[Otobreda]], developed originally from the [[Oto Melara]] [[76/62mm Allargato]], which was bigger, heavier and had a slower rate of fire. A vehicle-mounted version known as the [[Otomatic]] was built for the [[SPAAG|self-propelled anti-aircraft gun]] role, although this was not put into production.

The gun is capable of very high rates of fire, making it suitable for short-range anti-missile point defence. Its calibre also gives it abilities for anti-aircraft, anti-surface and ground shelling. Specialised ammunition is available for armour piercing, incendiary and directed fragmentation. A new stealth cupola has been designed in recent years.

The system is compact enough to be installed on relatively small warships, like [[corvette]]s, [[aviso]]s (a vessel somewhere between a corvette and a patrol boat), or [[patrol boat]]s. It has been widely exported and is in use with 53 navies. 

It has recently been favoured over the [[French 100 mm naval gun]] for the new [[Horizon CNGF]] frigates.

On 27 September 2006 [[Iran]] announced it has started mass production of a marine artillery gun, named the [[Fajr-27]], which is a [[reverse-engineered]] Oto Melara 76 mm gun.<ref>http://www.middle-east-online.com/english/?id=17626</ref>
