There have not been many Russian Doll season 3 updates, but there is a good reason to think there will be a third season coming to Netflix. After Netflix released Russian Doll season 1 in 2019, it was a long wait for the follow-up. Russian Doll season 2 arrived three years after season 1 because of filming delays related to the pandemic, but that helped justify the four-year time jump. With that said, the idea of a third season came up thanks to star Natasha Lyonne, but with her working on a new show called Poker Face, it makes one wonder if there will be time to make a third season.
