The first season of the American television series Jessica Jones, which is based on the Marvel Comics character of the same name, follows Jessica Jones, a former superhero who opens her own detective agency after her superhero career comes to an end at the hands of Kilgrave. It is set in the Marvel Cinematic Universe (MCU), sharing continuity with the films and other television series of the franchise. The season was produced by Marvel Television in association with ABC Studios and Tall Girls Productions, with Melissa Rosenberg serving as showrunner.

Krysten Ritter stars as Jones, while David Tennant plays Kilgrave. The two are joined by principal cast members Mike Colter, Rachael Taylor, Wil Traval, Erin Moriarty, Eka Darville, and Carrie-Anne Moss. Jessica Jones entered development in late 2013, with Rosenberg reworking a series she had previously developed for ABC. Ritter was cast as Jones in December 2014, and production took place in New York City from February to August 2015. The season addresses issues of rape and assault, and was always intended to be far more "adult" than other Marvel projects, particularly in terms of sex. The show's cinematography took inspiration from Neo-noir, while visual effects house Shade VFX focused on creating "invisible" effects that would support its realistic approach.

The first two episodes of the season premiered in New York City on November 17, 2015, with the full season of 13 episodes released on Netflix on November 20 to an estimated high viewership and critical acclaim. Critics praised the performances of Ritter and Tennant, as well as the season's noir tone, approach to sexuality, and coverage of darker topics such as rape, assault and posttraumatic stress disorder. The season was awarded a Peabody Award in the category of "Entertainment and Children's programs", and a Hugo Award for short form dramas. A second season of Jessica Jones was ordered on January 17, 2016.

In October 2013, Marvel Comics and Disney announced that Marvel Television and ABC Studios would provide Netflix with live action series centered around Daredevil, Jessica Jones, Iron Fist, and Luke Cage, leading up to a miniseries based on the Defenders. Melissa Rosenberg was brought on to showrun the Jessica Jones series, to be reconfigured as a "page one do-over" from an original project she had developed in December 2010 for ABC. In December 2014, the official title was revealed to be Marvel's A.K.A. Jessica Jones, but that was shortened to Marvel's Jessica Jones in June 2015. The season consists of 13 hour-long episodes.

The writers for the season worked in Los Angeles, with one member of the writing team on set in New York City for filming. Edward Ricourt, a member of Marvel Studios' writer program who had written a Luke Cage film script that had never come to fruition, was brought on to advise the series since it introduced the character. Actress Carrie-Anne Moss talked about how the scripts developed through the production of the season, explaining that the dialogue usually did not change much while filming, but scenes were altered to accommodate the filming locations when necessary. Rosenberg stated that, since Jones is a private investigator, there would be some procedural elements to the show, "but that's not our focus. There are cases. In particular, there is a large case that carries over the season." Elaborating on this, Marvel Television head Jeph Loeb said that the "fun about being a private detective is that the line between what's legal and what's not legal gets very blurred [...] her drive is not always necessarily to solve the case, as much as it is to go, 'Okay, can I pay the rent? How am I going to get through this day?'" He also added that inspiration for the season came from "the noir films from the '40s" and "film[s] like Chinatown."

Describing the tone of the season, Loeb said, "When we first started talking about Daredevil, we promised that we were telling a story that was first a crime drama and then a superhero show. This is more of a psychological thriller. This speaks to when you think about what happened to Jessica and what sort of destroyed her life and how she tried to put it together, and then to have to confront the person who deconstructed her world, that's a very powerful, emotional place to start from." On approaching rape and trauma in the season, Rosenberg wanted to avoid actually showing rape, which she called "lazy storytelling" and often a way to "spice up" male characters, and preferred to just make the trauma a part of the characters' everyday lives rather than an "issue" for the season to tackle. When asked about the adult nature of the season, including the use of sex, Rosenberg explained that Marvel would only not allow showing nudity and the use of the word "fuck" in the season. Regarding all of the social issues the season covered, such as "issues of choice, interracial relationships, domestic violence, [and] issues of consent" while also exploring "feminism and being a woman in this world", Rosenberg said, "It was never our intention going in [to hit a social issue], and I think the minute you intend to do that, you're stepping up on a soap box. If you're digging into the dark side of the human psyche and all the different experiences we go through, and as women we go through, you're going to find those things. If you treat them honestly and with respect, you're also going to hit social issues."

The main cast for the season includes Krysten Ritter as Jessica Jones, Mike Colter as Luke Cage, Rachael Taylor as Patricia "Trish" Walker, Wil Traval as Will Simpson, Erin Moriarty as Hope Shlottman, Eka Darville as Malcolm Ducasse, Carrie-Anne Moss as Jeri Hogarth, and David Tennant as Kilgrave.

Appearing in recurring roles for the season are Susie Abromeit as Pam, Colby Minifie and Kieran Mulcare as Robyn and Ruben, Nichole Yannetty as Nicole, Clarke Peters as Oscar Clemons, Michael Siberry and Lisa Emery as Albert and Louise Thompson, and Robin Weigert as Wendy Ross-Hogarth. Danielle Ferland, Gillian Glasco, Ryan Farrell, and Paul Pryce also recur as victims of Kilgrave who join a support group established by Jones, while Rosario Dawson and Royce Johnson reprise their roles of Claire Temple and Brett Mahoney, respectively, from Daredevil.
