Gwenpool (Gwendolyn "Gwen" Poole) is a fictional character appearing in American comic books published by Marvel Comics. Her physical design originated as an amalgam of Gwen Stacy and Wade Wilson on a variant cover of Deadpool's Secret Secret Wars #2, which was one of twenty variant covers published due to the popularity of Spider-Gwen from June 2015.

Marvel initially produced two stories featuring Gwenpool as a character, a backup story in the series Howard the Duck, and a one-shot Gwenpool Holiday Special. Following the publication of the one-shot, an ongoing series titled The Unbelievable Gwenpool by the same creative team was announced, which started in April 2016 and concluded in April 2018. The Unbelievable Gwenpool #0, collecting Poole's appearances from Howard the Duck and the first Gwenpool Holiday Special, was later released.

In June 2015, following the popularity of Spider-Gwen, all Marvel titles being published had alternate covers with Gwen Stacy reimagined as other characters, such as Doctor Strange, Groot and Wolverine. One of those was Deadpool, featured on Chris Bachalo's variant cover for Deadpool's Secret Secret Wars #2. After seeing how many fans were cosplaying as a character who was not even featured in any comic, Marvel editor Jordan White approached writer Christopher Hastings and editor Heather Antos with the task of creating a story around her. Initially the plan was to do one-shot comic "Gwenpool Special #1" (December 2015), which was then followed by introducing the character prior to the special with a three-issue backup story in the ongoing volume of Howard the Duck (November 2015-January 2016). After a meeting with White and Howard the Duck editor Will Moss, Hastings came out with the idea of a character aware of the fourth wall, "but it comes from this place of knowing she is in a comic book because she is from a world where the comic books actually exist", which would also initially lead to a cavalier attitude towards the world in which she inhabits "because she doesn’t believe there [are] any consequences to her actions", something Hastings summed as "she decides to [initially] use that [comic book] knowledge like she’s in Grand Theft Auto or something". A contrast would be that Gwenpool lacked any of the training or superpowers expected of Marvel characters.

The Howard the Duck arc, from November 2015 to January 2016, was drawn by Brazilian artist Danilo Beyruth, and the holiday special, published in December 2015, had art by Japanese duo Gurihiru. Once Marvel decided to make a Gwenpool ongoing series (named The Unbelievable Gwenpool), starting in April 2016, Hastings asked for Gurihiru's return to the artwork team, with the title being edited by Antos. The Unbelievable Gwenpool solo series ended at issue #25. Gwenpool would then join the revamp of the West Coast Avengers in 2018. Once that book ended, the character starred in the 2019 limited series Gwenpool Strikes Back, written by Leah Williams and drawn by Spanish artist David Baldeon.

Gwenpool has not been a contender in any CBUB matches.
