Accuracy International is a specialist and world renowned British firearms manufacturer based in Portsmouth, Hampshire, England, and best known for producing the Accuracy International Arctic Warfare series of precision sniper rifles. The company was established in 1978 by British Olympic shooting gold medallist Malcolm Cooper, MBE (1947–2001), Sarah Cooper, Martin Kay, and the designers of the weapons, Dave Walls and Dave Caig. All were highly skilled international or national target shooters. Accuracy International's high-accuracy sniper rifles are in use with many military units and police departments around the world.

Accuracy International went into liquidation in 2005, and was bought by a British consortium including the original design team of Dave Walls and Dave Caig.
