Harley Quinn Season 4 is on the way, so here’s everything we know so far, from the cast, plot details, and more.

After fears that the show would be canceled in the wake of Batgirl’s complete deletion and HBO’s trigger-happy atmosphere, fans can finally breathe, because Harley Quinn has been renewed for Season 4!

Now it’s time to start theorizing what is in store for Season 4 of the DC animated comedy, including potential release dates, plots, and which cast members will be returning.

One thing’s for certain though, if it follows the quality of the previous seasons, it’s gonna be great!

Is there a Harley Quinn Season 4 release date?

Harley Quinn Season 4 will release on Max on July 27, 2023.

This follows the show’s release pattern, as Seasons 1 and 2 came out within a year of each other, as will Seasons 3 and 4.

So you’ve only got a week left to make sure you’re all caught up!

Is there a Harley Quinn Season 4 trailer?

Yes there is. A new trailer was dropped on July 20, which you can watch below:

Harley Quinn Season 4 cast: Who will be retuning to the new season?

The expected cast for Harley Quinn Season 4 include the return of:

  • Kaley Cuoco as Harley Quinn
  • Lake Bell as Poison Ivy
  • Ron Funches as King Shark
  • Alan Tudyk as The Joker and Clayface
  • Diedrich Bader As Batman
  • Brianna Cuoco as Batgirl
  • Harvey Guillen as Nightwing
  • Sanaa Lathan as Catwoman
  • JB Smoove as Frank the Plant
  • Giancarlo Esposito as Lex Luthor

The crew is not staying quite the same this season, as the series is now getting a new showrunner. Sarah Peters, who has written on the series since Season 1 and is currently serving as a consulting producer, will take over the role from Patrick Schumacker and Justin Halpern, who originally developed the project with Dean Lorey.

When Schumacker and Halpern were asked about the change, they said they were “thrilled that this next season will be in great hands with Sarah Peters as our showrunner and Ceci Aranovich overseeing animation production, as they have both greatly influenced the show with their brilliance since the beginning.”

The series is and executive produced by Halpern, Schumacker, Cuoco, and Peters, along with Sam Register, Jessica Goldstein and Chrissy Pietrosh. It is produced by Delicious Non-Sequitur Productions and Yes, Norman Productions in association with Warner Bros Animation.

Harley Quinn Season 4 plot: What will happen in the new season?

Harley Quinn Season 4 will follow the wacky and exceedingly violent adventures of the powerful acrobatic villain – or ex-villain in this case.

Season 3 had been following Quinn and Ivy as they wrapped up their Eat Bang Kill! Tour and returned to Gotham as the new power couple. Alongside their crew, they strived to become the best version of themselves while also working towards Ivy’s plan of turning Gotham into an Eden paradise.

However, this ended with them making very different life paths – Ivy has joined Lex Luthor’s board, while Harley has joined the Bat-Family. No doubt Season 4 will look at how these separate careers will strain the couple.

Peter Girardi, EVP and Alternative Programming of Warner Bros. Animation, told Deadline: “Three seasons down and I can’t even begin to think about the new levels of chaos and trouble that Harley, Ivy and the gang can get into with a fourth season. But I’m grateful to our partners at HBO Max for continuing this insane ride with us so we can all find out.”

We will update this section as more information comes out.

Seasons 1-3 of Harley Quinn are available to stream on Max.
