The L118 light gun is a 105 mm towed howitzer. It was originally designed and produced in the United Kingdom for the British Army in the 1970s. It has since been widely exported. The L119 and the United States Army's M119 are variants that use a different type of ammunition.

The L118 uses separate-loading cased-charge ammunition – the projectile is loaded into the gun and rammed by hand, then the cartridge with propellant is loaded behind it. The L119 and M119 use "semi-fixed" ammunition – when it is prepared for firing, the projectile is fitted into the top of the cartridge case and the shell loaded into the gun as a complete round.
