Gwendolyne Maxine "Gwen" Stacy is a character appearing in American comic books published by Marvel Comics, usually as a supporting character in those featuring Spider-Man (Peter Parker). A college student and the daughter of George and Helen Stacy, Gwen was the first romantic interest for Peter following his high school graduation before she was murdered by the Green Goblin (Norman Osborn). Her death has haunted Peter ever since, and stories published long afterwards indicate she still holds a special place in his heart.
Gwen was posthumously subjected to numerous cloning experiments by her former professor Miles Warren, Peter's clone Ben Reilly, and an A.I. of Harry Osborn, the latter resulting in the creation of the Kindreds, and Ben briefly resurrecting Gwen in "Dead No More: The Clone Conspiracy" (2016–2017), with the embodiment of Death herself confirming in Ben Reilly: The Scarlet Spider (2017–2018) that all clones Ben created of deceased people had their souls intact on being brought back, while clones of living people (like Ben himself) had unique souls of their own. A flashback solo miniseries, Gwen Stacy: Beyond Amazing (2020–2024), was written by Christos Gage. In The All-New, All-Deadly Gwenpool (2025), she is again resurrected with Weapon X-like abilities under the designation X-31, teaming up with Peter, isekai protagonist Gwen Poole, and archer Kate Bishop against "The Great Architect". In the alternate universes of Ultimate Marvel, Spider-Gwen, and Ultimate Spider-Man, a still-living Gwen becomes their respective realities' versions of Carnage, Spider-Woman, and Mysterio.
