Seasons 1-5

Fringe is a sci-fi series that deals with parallel dimensions. In Season 2, episode 1's "A New Day in the Old Town," Senator James Van Horn's remarks suggest that this series takes place in the same universe as The X-Files. Not only is the X-Files referred to, but FBI agent Mulder is specifically referenced as having gone off the rails. The appearance of the X-Files episode "Dreamland" on television would seem to argue that The X-Files is a TV show in that universe, however, "Hollywood AD" showed that the adventures of Mulder and Scully had been turned into a movie. It's not known if that movie was later aired on TV (and that's what's being seen on television) or was spun off into a television series. It's also possible that in one universe, the X-Files is a television series, while in another it's history.

X-Files writer and producer Darin Morgan worked as a Consulting Producer on Fringe's third season. While this show's mythological focus on alternate dimensions might seem contrary to that of the X-Files, in fact, the X-Files ninth season episode "4-D" deals with that very subject.

Twin Peaks

The Return

Although there is no direct connection between the two shows, the series Fringe connects The X-Files to Twin Peaks, putting all three in the same universe. Fringe not only mentions a promising FBI agent named Mulder, who went off the rails, but features Doctor Jacoby's two-color glasses and says "they were sent to be by a Doctor Jacoby from Washington State."

David Duchovny, who plays FBI agent Fox Mulder  on the X-Files, played FBI agent Denise Bryson on Twin Peaks. She is transgender and once went by the name Dennis Bryson. She worked with Dale Cooper in 1987, went undercover for the DEA in 1988, and met with Cooper again in 1989. In 2014, she became the FBI Chief of Staff.

Trade pb: Millennium

In the year 2000, the end of the world - the anticipated "Millennium Event" - was avoided thanks to the efforts of Frank Black and FBI agents Fox Mulder and Dana Scully. Or was it? Frank's psychic gifts have been showing him that evil has continued to grow unabated in the world, and he's trying his best to ignore it. But soon the resurgence of the Millennium Group and their quest to find Frank's daughter, Jordan, will pull him into the fray once again.

Although the internal date is provided ("5,527 days since the new millennium"), this places this in 2015, which cannot be the case as Mulder is not back at the FBI. It likely reveals the "actual" date (see "Dating the X-Files and Millennium" for more info on this.)

When a blue-collar worker from New Jersey passes prophetic messages to the FBI from a mysterious "Mr. Zero," Mulder is convinced it is the same otherworldly entity that contacted the FBI through a suburban housewife in the 1940s. This similarly named "Mr. Zero" pointed the FBI toward many unusual cases, leading to the establishment of "the X-Files"!

 Flashback takes place in November 1946−January 1947. No discernable date is given for the frame story, which is being repurposed to a later date in order for it to fit with the Event Series.

Mr. Xero (or Zero) is established to be an alien entity from Zeta Reticuli that served to help the FBI solve cases involving supernatural elements, and whose name is the reason the X-Files are thus called.

Comic: The X-Files Season 10: Issues 1-5: The Believers

Hardcover: The X-Files Season 10, Vol. 1

Fox Mulder and Dana Scully—now living together in Spotsylvania County, Virginia under the aliases Anthony and Dana Blake—are visited by Deputy Director Walter Skinner, who informs them that an unknown person hacked into the FBI's files and discovered information regarding the X-Files. Skinner is later nearly killed in his hotel room, whereas Scully is met outside of the hospital by one of her patients, the young Emily Van de Kamp who is acting as if she were possessed; Scully is soon surrounded and brutally attacked.

FBI Agent John Doggett investigates a pipeline that mysteriously explodes. Meanwhile, Mulder tracks down the Lone Gunmen—revealed to have faked their deaths several years earlier—who attempt to help him find Scully. Scully, meanwhile, wakes up in a cabin surrounded by the mysterious Acolytes. She is subsequently saved by the ominous Deacon.

FBI Agent Monica Reyes investigates William's adoptive parents, only to discover their dead bodies in William's room, revealing that it was some unknown entities portraying the adoptive parents. Scully learns that she is being protected by the Deacon, and that the pipeline that Dogget was investigating is carrying magnetite. Mulder is visited by the believed-to-be dead Smoking Man, who behaves extremely oddly. Skinner tracks down Emily, only to discover tell-tale signs of acidic green alien blood.

Mulder visits the pipeline believed to be carrying magnetite and deduces that Scully has been taken into the surrounding woods. Meanwhile, Scully is taken by the Deacon to a general store, where she is picked up by an officer, who turns out to be a shape-shifting Acolyte; he transforms into Mulder, and Scully crashes the car. In the woods, Scully shoots the real Mulder, believing him to be Deacon. Mulder is healed by the Acolytes only to be tricked into thinking one of them is Scully. The real Scully, however manages to kill the impostor; suddenly she witnesses a massive alien space ship rise from the center of Yellowstone National Park, but begins to forget the encounter.

She reports to an FBI review board, headed by Skinner, and argues that people with connections to the X-Files division are systematically being targeted. To counter this, the FBI decides to reinstate Mulder and Scully as federal agents.

Dated 11 years after the birth of Scully's son William, which occurred some time in 2001, which places this series in 2012.  The story references protests against the "newly constructed Blackstone XL pipeline" in Crook County, Wyoming. While the name "Blackstone XL" can be considered as scornful epithet for the project by the Lone Gunmen, in fact, the ONEOK pipeline was granted eminent domain and began construction in November 2012 under much protest and controversy in Crook County, giving us a date for these stories. 

Mulder and Scully are reinstated to the FBI. Skinner is now Deputy Director. Both the Lone Gunmen and the Cigarette Smoking Man are revealed to be alive, though the latter seems to be no longer human. Agents John Doggett and Monica Reyes are abducted by the mysterious Acolytes.

William disappears.

Together they make dangerous revelations about the humanoid flatworm's ability to regenerate and procreate. Mulder survives a massive Flukeman attack in the sewers beneath Martha's Vineyard thanks to Scully's surgical skills, but he has developed an unnerving psychic connection to the creatures, providing him with a greater understanding of the nature of the organisms and their connection to the 1986 Chernobyl disaster.

Sequel to Season 2, episode 2: "The Host."

Mulder and Skully are back in the FBI for the first time, working under Assistant Director Anna Morales.

When an ancient weapon is discovered beneath a newly tapped oil field in Saudi Arabia, Agents Mulder and Scully find themselves pulled back into a black game as slippery as the X-Files. The dreaded "black oil" has been tapped in the remote deserts of the Middle East, and divergent forces are massing to contain, control, and even assist the deadly, sentient essence of Earth's once alien colonists. But what does it want with Agents Mulder and Scully, what does a rising neo-Syndicate want with it? And why, where, and—most importantly—how is Alex Krycek involved?!

Agent Mulder has been infected with black oil, playing host to an alien being seeking to use his knowledge, history, and expertise to unlock something mysteriously and terribly powerful. But Mulder and the would-be alien colonist possessing him aren't the only ones looking for it...

Alex Krychek is brought back to life. The Mulder-controlled black oil alien called Sheltem reveals to Scully that they are an alien race that came to Earth during the time of the dinosaurs, but were proceeded by another race that hunted them down.

The Cigarette Smoking Man is revealed, along with Krychek, X, and the Well-Manicured Man, to have been brought back to life by the "Glasses-Wearing Man" who displays telekinetic powers and controls the new syndicate.  At his behest, the Cigarette Smoking Man is killed by a duplicate of himself.

While The Ghostbusters universes can easily be made to fit into continuity, the fact that this storyline never occurred likely indicates it's not intended to be part of the X-Files universe, though an argument can be made that it might still be, though whether as a direct reflection of what was depicted in the two films and 147 episodes of the animated series (The Real Ghostbusters) or as dramatized versions or even entirely fictionalized versions of the "real" events is up to the reader/viewer to decide.

While The Teenage Mutant Ninja Turtles universes can be made to fit into continuity, the fact that this storyline never occurred likely indicates it's not intended to be part of the X-Files universe. One could argue that the grittier version depicted in the original 1984-1995 comic-book series (Volumes 1-2) is more likely a candidate for existing in the X-Files universe than the five lighter, family-friendly animated series or five live-action films that came later.
