## Premise

The series follows the adventures of Harley Quinn and her journey of self-discovery after breaking up with the Joker upon realizing that he never loved her. Harley intends to make a name for herself in Gotham City's criminal underworld, starting with the formation of her own crew, which consists of her best friend Poison Ivy, Clayface, Doctor Psycho, King Shark, and Sy Borgman. During her attempts to prove herself as a competent villain, Harley faces her troubled past, gains self-confidence that helps her abolish the Joker's influence on her, and finds an autonomous identity.
In addition to the adventures of Harley's crew, the main storyline revolves around the relationship between Harley and Ivy. Having met in Arkham Asylum when Harley was Dr. Harleen Quinzel and Ivy's therapist, the two developed a strong friendship that gradually deepened over the course of the series. They eventually realize they have feelings for each other despite Ivy's initial insecurity and her engagement with Kite Man. After a series of misadventures, during which Harley proves her selfish love to Ivy and Kite Man breaks up with her in favor of Ivy's happiness, Harley and Ivy become a couple by the end of season two. Over later seasons, the pair experience what it is to be in a healthy romantic relationship with mutual support, honesty, and self-determination.
As the series progresses, more DC characters gain a bigger role in the story, primarily the members of the Bat Family and members of the Legion of Doom as Harley and Ivy figure out their respective goals regarding those affiliations. Harley realizes she wants to help people rather than hurting them while Ivy discovers the true potential of her superpowers and develops a social conscience.
Apart from Harley and Ivy, other members of Harley's crew begin to follow their own path; Clayface breaks out as an actor, King Shark becomes a father and the ruler of the Shark Kingdom, and Psycho starts his own self-help podcast. Most of the seasons also contain a standalone episode that does not feature Harley or Ivy but focuses on one of the supporting characters, such as Joker, Batman, or Bane.

## Production
### Development

On November 20, 2017, it was announced that the then-unnamed DC Universe had ordered 26 episodes of Harley Quinn, a half-hour adult animated action-comedy series created and written by Justin Halpern, Patrick Schumacker and Dean Lorey. Executive producers were set to include Halpern, Schumacker, Lorey, and Sam Register with Jennifer Coyle serving as a producer. Production companies involved in the series were slated to consist of Ehsugadee Productions and Warner Bros. Animation. The first season consists of 13 episodes of the initial 26-episode order. Animation work is provided by NE4U, Digital eMation and Maven Image Platform in South Korea.
In June 2018, it was announced that the series would premiere in 2019. In October, it was further mapped as an October 2019 premiere. It was also reported that Kaley Cuoco would also serve as an executive producer for the series through her production company Yes, Norman Productions.
It was revealed that a second season was produced and consisted of another 13 episodes.
On September 18, 2020, three months after the second-season finale, it was announced that the series had been renewed for a third season, and would move to HBO Max. In February 2021, series creator Patrick Schumacker announced that they had begun recording season 3.
In June 2021, it was revealed that a planned oral sex scene between Catwoman and Batman in season 3 was cut by DC. It was replaced by a scene of Batman not being good at giving Catwoman a foot massage.
Schumacker stated the third season was more difficult to produce, but it will be much simpler not having to create two seasons back to back. Halpern has stated in an interview with Entertainment Weekly that season 3 will explore Harley's reaction to a half healthy relationship with Ivy as well as focusing more on Ivy's backstory as the previous two seasons were mainly focused on Harley. Schumacker said that new writers from the LGBTQ+ community have been hired because of the direction of season 2 and that it is a priority to diversify the staff for season 3. Schumacker also revealed that Dean Lorey would no longer be available to return as showrunner for season 3 and would be replaced by new co-showrunners Chrissy Pietrosh and Jessica Goldstein alongside him and Justin Halpern. Composer Jefferson Friedman revealed there would be a musical episode coming, and also stated that he wanted to refresh the music to give identity for each character. During an interview with Deadline Hollywood, Schumacker stated that his desire was to open season 3 on "an actual Zoom, where the GCPD is just being berated by the city of Gotham for their ineptitude". In February 2021, series creator Patrick Schumacker announced that they had begun recording season 3.
At DC FanDome 2021, Harley, King Shark, and Kite Man previewed some animatic footage from the third season, and announced it would be coming to HBO Max "sometime in 2022".
A comic prequel to season 3 was first released on August 3, 2021, under the title Harley Quinn: The Animated Series – The Eat. Bang! Kill. Tour by Tee Franklin (author), Max Sarin (cover art, penciller, inker), and Marissa Louise (colorist), in which Harley takes Ivy on a honeymoon where they face friends they've betrayed, their own feelings about how season 2 ended, and a few villains and heroes along the way. Commissioner Gordon tries to catch them repeatedly, causing Batman and Batgirl to worry about his sanity.
On August 9, 2022, it was announced that a fourth season is in development. On August 31, 2022, HBO Max renewed the series for a fourth season with Sarah Peters promoted to executive producer and showrunner, since Halpern and Schumacker will be busy with Kite Man: Hell Yeah!. On October 7, 2022, it was reported that the series is getting a holiday special called "Harley Quinn: A Very Problematic Valentine's Day Special" which was released in February 2023. On November 16, 2023, Max renewed the series for a fifth season, for which, Lorey became showrunner again.

### Casting

Alongside the series order announcement, it was reported that the producers of the series were expected to approach Margot Robbie, who portrays the character in the DC Extended Universe (DCEU), to reprise the role; but this was false. In an interview after the season 1 release, Halpern went on record saying Robbie was kept in the loop, but she was never interested in playing the role since she was filming and producing Birds of Prey at the time. Other characters expected to be featured in the series included Joker, Poison Ivy, Sy Borgman, Doctor Psycho, Malice Vundabar, King Shark, and Clayface.
On October 3, 2018, it was announced that Cuoco would voice Harley Quinn and Lake Bell would voice Poison Ivy. Additional voice actors in the series include Alan Tudyk as Joker and Clayface, Ron Funches as King Shark, J. B. Smoove as Frank the Plant, Jason Alexander as Sy Borgman, Wanda Sykes as the Queen of Fables, Giancarlo Esposito as Lex Luthor, Natalie Morales as Lois Lane, Jim Rash as Riddler, Diedrich Bader reprising his role from Batman: The Brave and the Bold as Batman himself, Tony Hale as Dr. Psycho and Christopher Meloni as James Gordon. Shortly after, Rahul Kohli revealed he would voice Scarecrow in the series. In June 2019, Sanaa Lathan was revealed to be voicing Catwoman, who was depicted as African-American. On July 24, 2019, Vanessa Marshall revealed to be reprising Wonder Woman from Justice League: Crisis on Two Earths and Justice League: The Flashpoint Paradox. While on the following day, TV Guide revealed that veteran voice actor Charlie Adler has been confirmed to serve as the series' additional voice director with Schumacker and Lorey serving as the voice directors. In February 2020, Alfred Molina was announced to be voicing Mr. Freeze. In April 2020, Schumacker confirmed that Michael Ironside would be reprising his role as Darkseid from both the DC Animated Universe and the Lego DC Super-Villains video game.
In June 2021, Sam Richardson was announced as having joined the cast as Swamp Thing. In March 2022, filmmaker–later co-chairman and co-CEO of DC Studios, James Gunn announced he will voice himself in the show's third season; the showrunners contacted him on Twitter about making an appearance, knowing he was a fan of the show. Gunn recorded his lines remotely, as he was directing his DCEU series Peacemaker in Vancouver, Canada, while season 3 was being developed. That same month, Harvey Guillén was cast to play Nightwing.
In December 2024, Stephen Fry was revealed to be voicing Brainiac along with Aisha Tyler as Lena Luthor.

### Music

Jefferson Friedman composed the music for the series. WaterTower Music released the soundtrack album for season 1 on August 21, 2020. The season 2 album was released on the same day.

### LGBTQ representation

In the DC Universe, Harley Quinn (Dr. Harleen Quinzel) and Poison Ivy (Dr. Pamela Isley) started as friends. In the comics, Harley and Ivy would refer to each other as "Peanut" and "Pam-A-Lamb". The writers took notice giving them moments of birthday kisses and taking showers together making their friendship more intimate. Harley Quinn's and Poison Ivy's relationship took a turn in Gotham City Sirens when Harley whispers into Ivy's ear that the reason she "saves her" from the Joker is due to her romantic feelings for her, although the scene ends with Harley going back to Joker. It was not until the 2013 Amanda Connor and Jimmy Palmiotti's Harley Quinn comic series where they are shown in a romantic coupling instead of friendship. Harley refers to Ivy as her "hot girlfriend" and the two are in an open relationship where they can pursue other partners while remaining dedicated to each other. Outside the main universe, Harley and Ivy even got married in Injustice 2.
In the May 15, 2020, episode "There's No Place to Go But Down" Harley Quinn saved her partner-in-crime, Poison Ivy; both kissed each other after they escaped from prison. One critic who reviewed the episode stated that Harley and Ivy's romance was a "slow burn", adding that this love affair could turn into a "more realistic exploration of how it feels to fall in love with a friend or to have an awkward hookup with a workmate". Another reviewer, Sophie Perry, writing for a lesbian lifestyle magazine, Curve, noted how queerbaiting has long endured in LGBTQ+ representation, noting how She-Ra and Harley Quinn both had same-sex kisses, happening within stories which could have turned out to be "typical queerbaiting" but did not. In another episode, Clayface, a member of Harley's villain crew, was revealed as a gay character who had a crush on a male student.
In 2021, the series was nominated for a GLAAD Media Award for Outstanding Comedy Series. The series was also nominated for several awards at Autostraddle's 4th Annual Gay Emmys, in the categories of "Best Episode with LGBTQ+ Themes" for the episode "Something Borrowed," and "Outstanding Animated Series". The trailer for the show's third season, which came out in October 2021, was described as showing that the series is "for the gays".

Caroline Framke of Variety wrote: "The animation feels like that of a typical Saturday morning cartoon, but its acidic scripts and shocking bursts of gore reminds you that Harley Quinn is taking full advantage of airing on a streaming service without censors. ... Sharp voice performances across the board from actors clearly relishing the chance to play in this world also prove too fun to resist. ... Most importantly, Harley gets to be an entire person all her own, as heartbreakingly naive as she is wickedly strange and funny." Robyn Bahr of The Hollywood Reporter wrote: "It's one of the best surprises of the year. ... 13 zippy, violent and irreverent half-hour episodes. ... The writing is frequently uproarious, chock full of Millennial nostalgia and cerebral gallows humor (the former may be low-hanging, rapidly-perishable fruit, but at least the show knows how to embrace its audience)."
