The CW's Supergirl drama series starring Melissa Benoist will conclude with the upcoming sixth season, set to premiere in 2021. This is the second series from the CW’s DC Arrowverse to come to an end following Arrow, which wrapped its eight-year run last season.

The producers, the studio, the network and Benoist came to a decision that it was better to end the show with a longer final season after facing production delay due to the coronavirus pandemic though a later start of production was already planned to accommodate the pregnancy of Benoist.
