In which city is the FBI headquarters located in The X-Files?

In The X-Files, the FBI headquarters is located in Washington, D.C. The city is the central institutional setting for the series because Mulder and Scully work as FBI special agents and regularly report to supervisors, attend briefings, and pursue cases from the capital.

Washington also anchors the show’s conspiracy storyline. The agents’ investigations repeatedly lead them into contact with senior officials, government buildings, classified records, military personnel, and covert organizations operating near the center of federal power. That setting makes the series’ tension between official authority and hidden information especially effective.

The FBI headquarters shown or referenced in the series is fictionalized as part of the show’s television world, but it draws on the real FBI headquarters in Washington, D.C., the J. Edgar Hoover Building. The building became a recognizable symbol of the Bureau after opening in the 1970s.

Viewers sometimes confuse Washington, D.C., with locations where the series was filmed. The early seasons were produced largely in Vancouver, Canada, before later production moved to Los Angeles. Filming location, however, does not change the fictional location of FBI headquarters.
