Development
In January 2020, The CW renewed the series for a sixth season. Jessica Queller and Robert Rovner return as the showrunners. In September 2020, it was announced that it would be the final season, with a 20 episode order. Nellie Andreeva from Deadline Hollywood stated the season's production delays, as well as the series' declining ratings, informed the decision to end the series with an extended final season.

Casting
Main cast members Melissa Benoist, Chyler Leigh, Katie McGrath, Jesse Rath, Nicole Maines, Julie Gonzalo, Staz Nair and David Harewood will return as Kara Danvers / Supergirl, Alex Danvers, Lena Luthor, Querl Dox / Brainiac 5, Nia Nal / Dreamer, Andrea Rojas, William Dey and J'onn J'onzz / Martian Manhunter.

Filming
Filming was initially scheduled to begin after Benoist returned from maternity leave, but was later rescheduled to begin on September 28, 2020. However, by September 29, filming was temporarily postponed, because of delays in receiving COVID-19 test results for the cast and crew. Filming ultimately began on October 13. The early filming of the season will film around Benoist's absence until she returns to work in January 2021. Filming is expected to conclude on August 6, 2021.

Marketing
In early August 2020, The CW released several posters of the Arrowverse superheroes wearing face masks, including Supergirl, with all posters having the caption "Real Heroes Wear Masks". This marketing tactic was used to "raise public awareness on the efficacy of facial coverings preventing the spread of COVID-19".

Broadcast
The sixth season is scheduled to premiere in mid-2021, and run for 20 episodes.
