A cloaking device is a form of stealth technology that uses selective bending of light to render a starship or other object completely invisible to the electromagnetic spectrum and most sensors. It has been encountered in varying forms over the centuries.

Certain parties are more prone to use cloaking technology to their advantage, as shown by Gippazoid Novelty Company and WD40's Ship.

Romulan Warbirds are also installed with cloaking devices.
