The X-Files Episode Order

X-files was the series that taught us to believe. It’s unique perspective on the science fiction genre resonated with much wider audiences, and even prompted several films and a revival more recently. This is the X-Files episode order and timeline.

What’s on The X-Files Episode Order?

The X-Files episode order includes all nine original seasons of The X-Files, as well as its continuing series, the films, and the spin-off series: Millenium and The Lone Gunmen.

This timeline does not include any of the books or comics based on the series. Though some of the comics were heralded as canon when they were first released, Chris Carter has stated that the new revival series did not follow that story-line. However, if you want to see a timeline that includes all of the comics anyway, check out this site. Otherwise, this chronological list only focuses on the on-screen canon, aka the shows and the films.

Where to Start?

As one might expect, the best place to start watching the X-Files is with the beginning of the series. It’s a long series, but you will find it difficult to understand what is going on if you jump in later in the series. The spin-off series are okay, but they pale in comparison to the original series. So start there first.
