A Surprising Update On ‘The Diplomat’ Season 4 Release Date On Netflix

The Diplomat season 3 has arrived with stellar review scores and an instant #1 placement on Netflix, so you may be wondering if that means a season 4 is definitely in the cards.

Yes, yes it is. The Diplomat was already renewed for season 4 way back in May of 2025, with Netflix expressing confidence in its breakout political drama. But that’s not the question, the question is when we’re going to see The Diplomat season 4’s release date, and there’s some additional good news on that front.

According to What’s On Netflix, filming for season 4 is allegedly about to start in just two weeks on November 3, 2025. That’s not even a month after season 3 has aired. So, what does that mean for the season 4 release date? Here’s the math:

  • Season 3 started filming in the summer of 2024, before season 3 was released in October 2025. Let’s say July, so that’s 15 months.
  • If Season 4 is filming in November 2025, 15 months from then is February 2027.

So, since filming started early on season 3, before season 2 even aired, it managed to make it out exactly a year after season 2. But since filming is starting later than that now, we’re looking at least a year and three months, so a bit extended. I’m not sure why they didn’t keep to the same filming schedule, but it seems The Diplomat will miss its “annual” release unless filming and post-production take less time this time around.
