The Nock gun was a seven-barrelled flintlock smoothbore firearm used by the Royal Navy during the early stages of the Napoleonic Wars. It is a type of volley gun adapted for ship-to-ship fighting, but was limited in its use because of the powerful recoil and eventually discontinued.

Its operation and historical importance has led to it being portrayed in modern fictional works, notably in The Alamo feature film, and the Richard Sharpe series of novels by Bernard Cornwell.
