After nine seasons on the air, The CW series "The Flash" is set to come to an end, with the upcoming ninth season confirmed to be the last one. Production on Season 9 is set to begin in September, with the final season slated to debut in 2023. The season will consist of 13 episodes. Previously Deadline reported speculation that Season 9 could be The Flash's final chapter in January when star Grant Gustin agreed to a one-year deal, capping his Season 9 involvement at 15 episodes. The CW in May announced that next season will be held for midseason.

“Nine seasons! Nine years of saving Central City while taking audiences on an emotional journey full of heart, humor, and spectacle,” said series executive producer and showrunner Eric Wallace. “And now Barry Allen has reached the starting gate for his last race. So many amazing people have given their talents, time, and love to bring this wonderful show to life each week. So, as we get ready to honor the show’s incredible legacy with our exciting final chapter, I want to say thank you to our phenomenal cast, writers, producers, and crew over the years who helped make ‘The Flash’ such an unforgettable experience for audiences around the world.“

The 13-episode midseason order would put the series finale just weeks ahead of the planned June 23 release of Warner Bros "The Flash" movie starring Ezra Miller as the title character. Coincidentally, the long-delayed film originally was announced just a week after The Flash series October 7 premiere on the CW. The series ending is expected to wrap its own storyline and not set up the movie in any way, according to the Deadline report.




The CW brass has been diligent about giving its signature series a proper ending, when possible. "The Flash" is one of two legacy shows whose next seasons will be the last, along with "Riverdale".

Upon the completion of its ninth season, “The Flash” will be one of the longest-running CW shows ever, particularly when looking at shows that originated solely on The CW. “Supernatural,” by comparison, ran for 15 seasons, but began its run on The WB before it became The CW. “The Flash” began airing on CW after the switch, airing its first episode in 2014.

“The Flash” is also the longest-running of The CW’s modern DC shows, edging out shows like “Arrow” (eight seasons) and “Legends of Tomorow” (seven seasons). “The Flash” has remained popular throughout its run and ended Season 8 as one of The CW’s most-watched shows and also ranked among its most-streamed titles. With it now ending, the only current DC shows on The CW are “Superman & Lois,” “Stargirl,” and the upcoming “Gotham Knights” series.

This is the latest legacy show at The CW to meet its end in recent months. The network previously canceled a number of its current series during upfront season, including “Naomi,” “Batwoman,” and “Legends of Tomorrow” as well as “4400,” “Charmed,” “Dynasty,” “Roswell, New Mexico,” and “In the Dark.” “Legacies” was also canceled in May, bringing the “Vampire Diaries” universe to a close. All of this has occurred as Nexstar is preparing to purchase a majority stake in The CW from Warner Bros. Discovery and Paramount Global. With the sale looming, questions arise about how much original scripted programming The CW will have going forward.

The Flash series currently stars Grant Gustin as Barry Allen/The Flash, Candice Patton as Iris West, Danielle Panabaker as Caitlin Snow, Danielle Nicolet as Cecile Horton, and Jesse L. Martin as Detective Joe West. Addional cast includes Danielle Nicolet, Kayla Compton and Brandon McKnight. Based on the characters from DC Comics, "The Flash" is from Bonanza Productions Inc. in association with Berlanti Productions and Warner Bros. Television, with executive producers Greg Berlanti, Sarah Schechter, and Todd Helbing.
