UFO conspiracy theories are a subset of conspiracy theories which argue that various governments and politicians globally, in particular the United States government, are suppressing evidence that unidentified flying objects are controlled by a non-human intelligence or built using alien technology.^[1] Such conspiracy theories usually argue that Earth governments are in communication or cooperation with extraterrestrial visitors despite public disclaimers, and further that some of these theories claim that the governments are explicitly allowing alien abduction.^[2]

Individuals who have suggested that UFO evidence is being suppressed include Stanford University immunologist Garry Nolan,^[3][4] United States Senator Barry Goldwater, British Admiral Lord Hill-Norton (former NATO head and chief of the British Defence Staff), American Vice Admiral Roscoe H. Hillenkoetter (first CIA director), Israeli brigadier general Haim Eshed (former director of space programs for the Israel Ministry of Defense),^[5] astronauts Gordon Cooper^[6][7] and Edgar Mitchell,^[8] and former Canadian Defence Minister Paul Hellyer. Beyond their testimonies and reports they have presented no evidence to substantiate their statements and claims. According to the Committee for Skeptical Inquiry little or no evidence exists to support them despite significant research on the subject by non-governmental scientific agencies.^{[9][10][11][12]}

Scholars of religion have identified some new religious movements among the proponents of UFO conspiracy theories, most notably Heaven's Gate, the Nation of Islam, and Scientology.^[1]
