The Purple Ray is a fictitious healing device that appears in the Wonder Woman comics published by DC Comics. It was created at the beginning of the Golden Age by the scientific and (ex-) German spy, Baroness Paula von Gunther.

The concept survived on Earth-1 and on the continuities post-Crisis and post-Zero Hour.

It deserves to be mentioned that the Purple Ray was what restored Steve Trevor's health, and that it was also modified to transfer the power of several Amazons from Paradise Island to Donna Troy so that she could have her own powers. On another occasion, he was employed to revive Changeling of the Young Titans, which somehow increased his powers in the process.

In the Modern Era, the Purple Ray is able to completely heal a wide range of wounds, except the most serious ones since prolonged exposure to lightning can exhaust a person's natural healing ability. In cases of a serious injury, it is possible to expose the injured person to small doses of lightning for a longer period. In addition, the Purple Ray can not heal wounds caused by the gods or their agents, such as the Gorgon.

In Crisis Infinita N ° 3 (December 2005), a "purple ray of death" appears.
