The X-Files in Order

Eleven seasons and 218 episodes: nine original seasons from 1993 to 2002 with 202 episodes, then a six-episode season 10 in 2016 and a ten-episode season 11 in 2018. There are also two films, Fight the Future (1998) and I Want to Believe (2008).

Broadcast order, with Fight the Future between seasons 5 and 6 and I Want to Believe between season 9 and the revival. The first film is the one placement people get wrong: it was written as a bridge, season 5 ends with the X-Files shut down and the film reopens them, so saving it for after the series breaks both the film and season 6.

Effectively yes. Season 6 opens with the characters dealing with the film's consequences and does not re-explain them. It is the one part of The X-Files that is genuinely required viewing in its exact slot.

Roughly a quarter of the 218 episodes carry the continuing alien conspiracy story; the rest are standalone cases. If you want an official answer rather than a fan list, Fox's four mythology DVD collections, Abduction, Black Oil, Colonization and Super Soldiers, contain the arc episodes as the producers counted them. The standalones are skippable for plot, though many of the show's best episodes are standalones, so skipping them all is a poor trade.

You can stop after season 7 or the film and have most of an ending, but seasons 8 and 9 are where the mythology actually concludes, in the two-part finale The Truth. Season 8 in particular is more serialised and better regarded than its reputation suggests. If you watch the revival, you need the broad strokes of both.

As a mythology chapter, no; it is a standalone case with no aliens. As an epilogue about where Mulder and Scully ended up six years after the finale, it has its defenders. Nothing in the revival requires it, though the revival does acknowledge it.

They are optional in a way the original run is not. Seasons 10 and 11 reopen the mythology after The Truth closed it, and their reception was mixed, with the standalone episodes rating far better than the arc ones. If you want the series as it stood for fourteen years, stop after season 9 or I Want to Believe. If you want everything, the revival contains a handful of episodes that stand with the show's best.

In practice, yes. Season 11 ended in March 2018, Gillian Anderson has said she will not return as Scully, and no continuation has been announced since. Chris Carter has spoken about the future of the franchise in interviews, but as of 2026 nothing is in production.

In the US the full series has streamed on Hulu, with the two films available to rent digitally. Disney+ carries the series in many other regions. Availability rotates, so check JustWatch for your region.

The 218 episodes run about 160 hours, and the two films add roughly four more. At an episode a day it is about seven months; the mythology track alone, at around a quarter of the episodes, is closer to six weeks at the same pace.
