'The Diplomat’ season 3 set for 2025 release with new cast and longer episodes

OTT has officially announced that filming for Season 3 of 'The Diplomat' has been completed, and the new season is expected to premiere sometime in 2025.
According to OTT 2025 lineup announcement, the political drama series will return with eight episodes, bringing back the same number of episodes as Season 1 after a shorter six-episode Season 2.
Filming for Season 3 began during the summer of 2024 and later moved to New York City. The production quietly wrapped up ahead of schedule in March 2025, even though filming was initially planned to go until March 20. Crew members reportedly confirmed the early wrap on social media, but an official statement was made on January 30, 2025, "Next on Netflix" presentation, where fans also got a sneak peek at the upcoming season.
OTT had already quietly renewed the series for Season 3 before making it official, showing that the platform had confidence in the show’s continuation. However, there is still no confirmation about a fourth season, especially since Season 2 didn’t receive the same level of response as the first season.
Season 3 will feature some new cast members, including Bradley Whitford, who is known for his role in The West Wing. He will reunite with Allison Janney, another veteran from the same series. In addition to them, Nathan Wiley and Mercer Boffey are expected to appear, likely taking on the roles of Agent Crocker and the Deputy Chief of Staff, respectively.
Behind the scenes, the writing team includes several familiar names from previous seasons. Debora Cahn, the series creator, has written the first and final episodes (301 and 308). Other writers contributing include Anna Hagen, Eli Attie, Jessica Brickman, Peter Noah, Peter Ackerman, and Julianna Dudley Meagher. Alex Graves will return as a director for the new season.
While fans are happy to know that Season 3 is coming soon, they are still waiting to hear whether Netflix will give the green light for more seasons in the future. For now, excitement is building for the release of eight new episodes filled with drama, politics, and diplomacy when 'The Diplomat' returns in 2025.
