The seventh season of The Flash premiered on The CW on March 2, 2021, and concluded on July 20, 2021. It was announced on January 7, 2020.[1]

The season aired on Tuesday nights at 8:00 PM prior to Superman & Lois during the first four weeks of March, Supergirl from March 30 to May 11, and Superman & Lois again for the remainder of the season.

It arrived on DVD and Blu-ray on September 28, 2021.

Season seven is split into multiple graphic novels, starting with the continuation of the previous season's Reflections and Lies arc, episodes 1 to 3; then God Complex, episodes 4 to 11; Interlude I, episodes 12 to 14; and The Godspeed Imperative, episodes 15 to 18.


"Barry Allen lived a normal life as a perpetually tardy C.S.I. in the Central City Police Department. Barry’s life changed forever when the S.T.A.R. Labs Particle Accelerator exploded, creating a dark-matter lightning storm that struck Barry, bestowing him with superspeed and making him the fastest man alive — The Flash. After a thrilling cliffhanger last season which saw the new Mirror Master victorious and still-at-large in Central City, The Flash must regroup in order to stop her and find a way to make contact with his missing wife, Iris West-Allen.

With help from the rest of Team Flash, which includes superheroes Caitlin Snow, Cisco Ramon, Ralph Dibny, and Nash Wells, as well as the Flash’s adoptive father Joe West, Meta-Attorney Cecile Horton, tough cub reporter Allegra Garcia and brilliant tech-nerd Chester P. Runk…Flash will ultimately defeat Mirror Master. But in doing so, he'll also unleash an even more powerful and devastating threat on Central City: one that threatens to tear his team—and his marriage—apart."[2]

Critical response


The seventh season premiere of The Flash received a viewership of 1 million and an 18-49 demographic rating of 0.3, a 0.1 decline from the season six finale that aired ten months prior. The first, second, sixth, and seventh episodes of the season were the only ones to earn a 0.3 rating. Episode two marked the first episode of The Flash to fall under 1 million in live viewership. The following week's March 16 episode marked a new series low of 0.2, a rating earned by most episodes in the season; however, the two April episodes both earned 0.3 ratings. The Flash hit yet another series low (0.1 rating) on its May 25 episode, but rose back up to 0.2 on its June 8 episode and continued steady until the season finale on July 20. Despite the 50 percent drop in mean demographic rating from the sixth season, The Flash remained one of the top performers of The CW's 2020-21 season, alongside newcomers Walker, Superman & Lois, and Kung Fu.


  • The first trailer was released on August 22, 2020.[13]
  • The premiere date for the season was re-scheduled twice. On May 14, 2020, it was announced that the season would debut in January 2021.

  • On May 4, 2021, it was announced that Tom Cavanagh and Carlos Valdes would be departing as series regulars after seven seasons.[17]
  • This is the first season of The Flash to:
    • Not premiere in the month of October

    • Air episodes in the months of June and July
    • Not conclude in the month of May

  11. Hartley Sawyer (@hartleysawyer) on Instagram: "My words, irrelevant of being meant with an intent of humor, were hurtful, and unacceptable. I am ashamed I was capable of these really horrible attempts to get attention at that time. I regret them deeply. This was not acceptable behavior. These were words I threw out at the time with no thought or recognition of the harm my words could do, and now have done today. I am incredibly sorry, ashamed and disappointed in myself for my ignorance back then. I want to be very clear: this is not reflective of what I think or who I am now. Years ago, thanks to friends and experiences who helped me to open my eyes, I began my journey into becoming a more responsible adult - in terms of what I say, what I do, and beyond. I've largely kept that journey private, and this is another way that I have let so many down. I still have more work to do. But how I define myself now does not take away the impact of my words, or my responsibility for them. I am very sorry."
