Netflix has firmly established itself as a home for gripping political thrillers, from the intricate White House drama of The Diplomat to the high-stakes espionage of The Night Agent. These series captivate audiences by blending complex political machinations with personal betrayals and moral dilemmas. Now, with a new season on the horizon and a confirmed future, one of these celebrated shows, The Diplomat, is set to continue its gripping narrative and open the fourth door.

The series has already been given a green light for its future, ensuring its gripping story will unfold over an even longer period.

Netflix has already confirmed the fourth season of the show. According to production schedules, filming for Season 4 is slated to begin on November 3, 2025. The production will again be split between London and New York. While a specific end date has not been provided, filming is expected to last for a significant portion of 2026, possibly wrapping up in early July. This timeline suggests a late 2026 release is a possibility, though an early 2027 release seems more probable.

This early renewal was announced in May 2025 as part of the streaming service’s Upfront presentation, which also included renewals for several other popular shows. The early greenlight for another season demonstrates Netflix's confidence in the series and its long-term viability, despite a reported viewership drop between its first two seasons. The network is clearly invested in its future.

This confidence in the series' future is well-placed, as the immediate focus turns to the highly anticipated third season.

Before Season 4 arrives, fans are looking forward to an expanded third season, which premieres on October 16, 2025. In Season 3, the protagonist faces the consequences of her past actions. She had previously accused the Vice President of a terrorist plot and confessed her own political ambitions. The President's sudden death places her in a challenging position, a role she never wanted.

With the new President in power, the protagonist is pushed by her husband to secure the vice presidency. She must navigate her newfound freedom, a complicated relationship with the Foreign Secretary, and a disconcerting connection with the First Gentleman. This season is poised to be a dramatic turning point for the series, setting up the political landscape for the confirmed fourth season.
