The 9-inch cannon at Simon's Town is a rifled muzzle loading (RML)cannon with a bore diameter of 9 inches, located at Middle North Battery.

This cannon was placed in its position by the British.

With the commissioning of more modern cannon in defense of the Simon's Town coast line, the 9-inch cannon became obsolete and was abandoned to vandalism and deterioration. That was until Warrant Officer (Class 1) Harry Croome, a member of the Cannon Association of South Africa (CAOSA) succeeded in becoming the custodian of the cannon. Since then the cannon was restored as far as possible and was proof fired again for the first time in 108 years before the Navy Festival of April 2011.

The historicity of this proof firing is emphasised by the fact that no one present at the previous firing of the cannon was alive anymore.

The 9-inch is still fired at special occasions like the commemoration of Heritage Day, Youth Day, Freedom Day, Reconcilliation Day and during the annual Navy Festival.
