Keri Russell’s disheveled diplomat Kate Wyler has some big shoes she’s about to (be forced to) fill. After season 2 of Netflix’s political drama The Diplomat ended on a huge twist, the series is barreling toward a third chapter—one with major implications for Kate’s career, widening the target already strapped to her back. Here’s what we know so far about the series’ third season, which Netflix confirmed prior to season 2’s release.
Will there be a season 3 of the The Diplomat?
Yes. Before season 2 hit screens in October 2024, Netflix shared the news that The Diplomat would receive a season 3—and that, in fact, production was already underway in London and New York City.
“After an amazing summer shooting in the UK, we brought London home to NY,” said series creator Debora Cahn in a statement. “Best of both worlds—filming in Brooklyn. We love doing this. We’re so excited to get to keep going.”
Who will be in the cast?
Expect many of the main players to return, including Russell as Kate, Rufus Sewell as Kate’s ambassador husband Hal Wyler, Allison Janney as U.S. Vice President Grace Penn, David Gyasi as British Foreign Secretary Austin Dennison, Ali Ahn as London CIA Chief Eidra Park, Rory Kinnear as Prime Minister Nicol Trowbridge, and Ato Essandoh as Deputy Chief of Mission Stuart Hayford.
Netflix also announced that Bradley Whitford is joining the cast as Todd Penn, Grace Penn’s husband, marking a West Wing reunion for him and Janney.
When will The Diplomat season 3 come out?
The Diplomat will return to Netflix on Oct. 16, 2025.
