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.
That said, 15 months is still less than almsot all streaming productions. The floor is usually closer to a year and a half, and on bigger shows, two years is almost standard. If The Diplomat can keep within this range, that’s still “good enough” compared to the larger catalogue of Netflix shows, and really, streaming in general.
The Diplomat may not put up record Netflix numbers, but it’s arguably the best political drama airing right now. Some are calling it the new West Wing, which is funny given that two West Wing actors, Allison Janney and Bradley Whitford are the President and First Gentleman on the show, respectively, as of this season.
The Diplomat season 3 is likely to be planted on top of Netflix’s top 10 list for quite a while. Well, at least until the season finale of Love is Blind airs to knock it off temporarily. But it’s another hit season, and hopefully season 4 will be the same.
