Klingon disruptors were a type of hand-held disruptor weapon used by Klingon officers.

They cause damage by exciting the molecular bonds of targets to such great extents that those bonds were weakened, and/or broken, by the energies emitted. They could fire a particle beam or a burst of energy.

These weapons came in two styles, a pistol sidearm which was kept in a holster, attached to the Klingon uniforms and a larger rifle. The rifles were capable of full automatic fire, and used energy cells as ammunition. They were capable of vaporizing a humanoid target, and had at least two settings, though none were stun.

There have been multiple variations of the weapon throughout the 22nd, 23rd, and 24th centuries.
