The Flash season 9 is the show’s final, and there are not too many episodes left before the Arrowverse’s longest-running series comes to an end. The Flash season 9 had the difficult mission of wrapping up the stories of Barry Allen and his family while also concluding the Arrowverse. As a result, some of The Flash season 9 episodes have featured several connections to the Arrowverse’s multiverse, while others have been more focused on Barry Allen.

The Flash season 9 has explored a number of storylines, including having Barry Allen face off against the DC villain Red Death. Once that particular villain was unmasked - revealed to be an evil version of Ryan Wilder's Batwoman - The Flash continued its story and featured the return of Stephen Amell’s Oliver Queen from Arrow one last time before the Arrovwerse ends. Now, The Flash season 9’s story is coming to an end.

How Many Episodes Does The Flash Season 9 Have?

The Flash season 9 has 13 episodes, making it the shortest The Flash season. The Flash season 9, episode 10, “A New World, Part One: Reunions,” was the first of a four-part arc that will conclude the series and, presumably, the Arrowverse as a whole. The most recent episode was The Flash season 9, episode 12, “A New World, Part Three.” Therefore, there is only one episode left in The Flash season 9. That episode is “A New World, Part Four.”

The announcement that The Flash’s final season would be the show’s shortest was no surprise. Although some TV shows end up being canceled before the story can be wrapped up, The Flash’s writers knew beforehand that season 9 was going to be the series’ last. Therefore, a shorter, more centered season was created to conclude the story. As a comparison, Arrow season 8, the show’s final, had 10 episodes.
