The Infinity Gems, originally referred to as Soul Gems, are six immensely powerful fictional gems appearing in American comic books published by Marvel Comics. Whoever holds all six gems and uses them in concert, such as in the Infinity Gauntlet, gains virtual omnipotence and omniscience. The six primary gems are the Mind Gem, the Soul Gem, the Space Gem, the Power Gem, the Time Gem and the Reality Gem, and in later storylines, crossovers and other media, a seventh Infinity Gem is sometimes added. The Gems play a prominent role in the first three phases of the Marvel Cinematic Universe, where they are known as the Infinity Stones.

The Soul Gems first appear in The Power of Warlock. All six appear together for the first time in the second "Thanos War" storyline in Avengers and Marvel Two-In-One annuals. Thanos harnesses their latent energies to power a giant gem to extinguish every star in the universe.

In the third volume of the Silver Surfer title, the Surfer refers to the gems as "Soul Gems" for the first time. They are gathered by the Elders of the Universe, who intend to use their combined power to drain Galactus of his lifeforce and then recreate the universe with themselves as the oldest beings in it (Galactus was the last survivor of the Universe that existed prior to the birth of the current Marvel Universe). This plot is thwarted by the Silver Surfer, and several Elders and the gems are lost in a black hole; Galactus consumes some of the other Elders. In a follow-up story, Galactus is poisoned by the Elders he consumed. Silver Surfer, Mr. Fantastic, and the Invisible Woman journey through the black hole to recover the gems. Invisible Woman becomes possessed by the sentient Soul Gem, awakening her evil Malice persona. She is later subdued, and the gems are used to remove the Elders from Galactus' body. The Elders later reclaim the gems.
