"The Truth" is the finale of the ninth season of the American science fiction television series The X-Files. "The Truth", the 19th and 20th episodes of the season and the 201st and 202nd episodes overall, originally served as the finale for the entire series, until the return of the series in January 2016. First aired together on the Fox network on May 19, 2002, the episodes were written by series creator Chris Carter and directed by Kim Manners. "The Truth" was the most-watched episode of the ninth season and was seen by 13.25 million viewers upon its initial broadcast.
