The QF 3-pounder Nordenfelt was a light 47 mm quick-firing naval gun and coast defence gun of the late 19th century used by many countries.

The United Kingdom only deployed this gun for coast defence, and soon discarded it in favour of the similar QF 3-pounder Hotchkiss gun for both coast defence and naval use.

Ammunition was in "fixed rounds" : the projectile and brass cartridge case were loaded as a single unit. The gun used the same ammunition as the similar QF 3-pounder Hotchkiss, with either Nordenfelt or Hotchkiss fuzes. When introduced in the 1880s the propellant used was gunpowder, in British service Cordite Mark I was used as propellant from the mid-1890s onwards.
