Birdgirl is an American adult animated superhero comedy television series. It is a spiritual successor to the television series Harvey Birdman, Attorney at Law created by Michael Ouweleen and Erik Richter, which itself was a comedic spin-off of the original 1967 Birdman cartoon and Space Ghost Coast to Coast. The series stars the voices of Paget Brewster, Rob Delaney, Sonia Denis, Kether Donohue, John Doman, Negin Farsad, Tony Hale and River L. Ramirez. The series premiered on Adult Swim on April 5, 2021. Unlike in the original Birdman cartoon, the Hanna-Barbera-owned characters—including Birdman himself—are missing from the series.

On October 4, 2021, Kether Donohue, the voice of Gillian, posted on Instagram that Birdgirl had been renewed for a second season. This was confirmed on February 9, 2022. The second and final season premiered on Adult Swim on June 19, 2022, and HBO Max on June 20.
