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 will arrive on DVD and Blu-ray on September 28, 2021.[2]

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."[3]

  12. 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."
