Jessica Campbell Jones is a fictional superhero appearing in American comic books published by Marvel Comics. The character was created by writer Brian Michael Bendis and artist Michael Gaydos, and first appeared in Alias #1 (November 2001), as part of Marvel's Max, an imprint for more mature content. Within the context of Marvel's shared universe, Jones is a former superhero who becomes the owner (and usually sole employee) of Alias Private Investigations. Bendis originally envisioned the series centered on Jessica Drew and only decided to create Jones once he noticed that the main character had a distinct voice and background that differentiated her from Drew.
Jones has since starred in three ongoing series: Alias, The Pulse and Jessica Jones. Alias ran for 28 issues before ending in 2004, while The Pulse ran for 14 issues from April 2004 to May 2006. Jessica Jones debuted in October 2016. She became a member of the New Avengers, alongside her husband, Luke Cage, during Marvel's 2010 Heroic Age campaign. She has used various aliases throughout her history, including Jewel, Knightress, and Power Woman.
The character was portrayed by actress Krysten Ritter in the Marvel Cinematic Universe, starring in Marvel's Jessica Jones (2015–2019) and The Defenders (2017). She has also been featured in various video games, in which she has been voiced by several actresses including Michelle Phan, Mary Elizabeth McGlynn and Tara Strong.
