"Tunguska" is the eighth episode of the fourth season of the American science fiction television series The X-Files. It premièred on the Fox network on November 24, 1996. It was directed by Kim Manners, and written by Frank Spotnitz and series creator Chris Carter. "Tunguska" featured guest appearances by John Neville, Nicholas Lea and Fritz Weaver. The episode helped explore the series' overarching mythology. "Tunguska" earned a Nielsen household rating of 12.2, being watched by 18.85 million people in its initial broadcast.
In the episode, FBI special agent Fox Mulder (David Duchovny) travels to Russia to investigate the source of a black oil contamination. His partner Dana Scully (Gillian Anderson) and assistant director Walter Skinner (Mitch Pileggi) are summoned to attend a United States Senate hearing on Mulder's whereabouts. "Tunguska" is a two-part episode, with the plot continuing in the next episode, "Terma".
"Tunguska" was inspired by reports of evidence of extraterrestrial life possibly being found in the Allan Hills 84001 meteorite, while the gulag setting was inspired by the works of Aleksandr Solzhenitsyn. The story offered the writers a chance to expand the scale of the series' mythology globally, although production of the episode was described as troublesome and expensive.
