The third season of the American science fiction television series The X-Files commenced airing on Fox in the United States on September 22, 1995, concluded on the same channel on May 17, 1996, and contained 24 episodes. The season continues to follow the cases of FBI special agents Fox Mulder and Dana Scully, portrayed by David Duchovny and Gillian Anderson respectively, who investigate paranormal or supernatural cases, known as X-Files by the FBI.

The season features the conclusion of several plot-lines introduced in season two, while also introducing several new plot elements. Major plot arcs include an elaborate conspiracy being discovered when an alien autopsy video is acquired by Mulder, Scully's search for the killer of her sister, and the mystery surrounding X (Steven Williams). Pivotal characters such as the First Elder (Don S. Williams) and the alien virus black oil were first introduced in this season. In addition, the season features a wide variety of "Monster-of-the-Week" episodes, stand-alone stories not of influence to the wider mythology of the series.

The season attained higher ratings than season two, the highest viewing audience the series had yet achieved. Season premiere "The Blessing Way" debuted with a Nielsen household rating of 19.94, which more than doubled the premiere of the last season. The ratings consistently stayed above 15.0, making it one of the most watched series of the 1995–96 television line-up. The season received generally positive reviews from television critics, winning five Primetime Emmy Awards. Many of the episodes written by writer Darin Morgan received critical acclaim, including the episodes "Clyde Bruckman's Final Repose" and "Jose Chung's From Outer Space" which are often cited as some of the best of the series. Morgan left the series following this season, due to an inability to keep up with the fast-paced nature of the show.

Plot overview

<!-- Don't include any summary from the non-mytharc episodes since they are stand alone episodes. -->

The show centers on FBI special agents Fox Mulder (David Duchovny) and Dana Scully (Gillian Anderson) who work on cases linked to the paranormal, called X-Files. Mulder is later found in the desert following the events of the second season finale and nursed back to health by Albert Hosteen (Floyd Red Crow Westerman). Meanwhile, Scully investigates the possible involvement of the smallpox eradication program in human genetic experimentation, discovering that a Nazi scientist who defected during Operation Paperclip has been conducting human experimentation to create alien-human hybrids. Her sister Melissa (Melinda McGraw), however, is shot by assassins who mistake her for Dana, and dies in hospital that night.

Investigating evidence of an alien autopsy, Mulder infiltrates a secretive government train carriage carrying an alien-human hybrid. Mulder is almost killed by a Syndicate operative guarding the hybrid, but is saved by his informant X (Steven Williams). X had been tipped off about Mulder's activities by the agent's partner Dana Scully (Gillian Anderson). Scully, meanwhile, meets a group of women with abduction experiences similar to her own, and meets another member of the Syndicate known as the First Elder (Don S. Williams), who claims during her abduction she was placed on a similar train car and experimented upon by the Japanese scientists.

The crew of a French salvage ship trying to raise a World War II-era submarine from the sea floor are stricken with massive radiation burns—except for one, who has been infected with a parasitic black oil discovered on the submarine. The oil is controlling the crewman's body, and after passing through several hosts, has overtaken Alex Krycek (Nicholas Lea), whom Mulder has been pursuing. Scully finds that the submarine had been involved in discovering the oil on the sea floor during World War II, under the guise of finding a sunken fighter plane. The infected Krycek makes his way to a missile silo used to hide a UFO, and the oil escapes his body to board the craft. Meanwhile, Scully has tracked down Luis Cardinal, the man responsible for killing her sister.

Writing

upright|thumb|As with season two, [[David Duchovny received two writing credits in season three, including for the season finale.]]

Development of the first episode of the season, "The Blessing Way", began with the second-season finale "Anasazi". Both of those episodes, along with "Paper Clip", form a trilogy of episodes that began the third season. Morgan's first sole credit as a writer came in the episode "Humbug", which received a positive reception by the staff. David Duchovny expressed an enjoyment for working with Morgan, commenting "what I loved about his scripts was that he seemed to be trying to destroy the show." Other episodes dealing with the wider mythology of the series—"Talitha Cumi", "Piper Maru" and "Apocrypha"—explore similar concepts, showcasing the shadow government plot line of the series. "Oubliette" offers a sentimental and emotional plot driven by the kidnapping of a young girl. The episode features parallels to the real life Polly Klaas case and provides commentary on both stockholm syndrome and trauma.

Aliens and serial killers are not the only antagonists in the season; several episodes revolve around more traditional, B-movie inspired monsters, taking influence from horror films. These episodes include "War of the Coprophages" and "Quagmire", about killer cockroaches and a lake monster. Both "Clyde Bruckman's Final Repose" and "Jose Chung's From Outer Space" play against tropes and the established formula of the series, subverting themes the series usually followed.
