Gideon the Elder is a Whitelighter Elder on the television show Charmed.

Gideon is known as the headmaster of the Magic School.

One of the most powerful Elders, Gideon was entrusted with the position as headmaster of Magic School, an institution where young magical beings can learn about magic.

While he originally pushed for the Elders to allow Piper Halliwell and Leo Wyatt to get married, once Wyatt Matthew Halliwell was born, Gideon's attitude toward the couple changed drastically. He feared that all of the power that Wyatt possessed would cause him to turn and become an unstoppable threat.

Gaining the sisters' confidence, Gideon used his position as a friend of the family to get close to Wyatt and hired a team of darklighters to get Leo out of the way.

He conspired with his evil counterpart in a parallel dimension to distract both the good and evil Charmed Ones so that he might kill Wyatt. The sisters realized his plan in time and stopped him, but only temporarily. Conspiring with Barbas who used his powers to distract the sisters and Leo, Gideon managed to kidnap Wyatt, killing Chris in the process. Angered by his son's death, Leo tracked Gideon down in the Underworld and killed him.
