List of denaturalized former citizens of the United States

This is a list of denaturalized former citizens of the United States, that is, those who became citizens through naturalization and were subsequently stripped of citizenship. In the cases of Solomon Adler and Bhagat Singh Thind, they subsequently obtained United States citizenship. Frank Walus's nationality was restored after doubts emerged as to the accuracy of the complaints against him and his conviction was quashed.

According to a February 2, 2011 release from the United States Department of Justice, since 1979, the federal government has stripped 107 people of citizenship for alleged involvement in war crimes committed during World War II through the efforts of the Office of Special Investigations (OSI). An unabridged 600-page Justice Department report obtained by The New York Times in 2010 stated, "More than 300 Nazi persecutors have been deported, stripped of citizenship or blocked from entering the United States since the creation of the O.S.I." The Los Angeles Times reported in 2008 that five such denaturalized men could not be deported as no country would accept them, and that four others had died while in the same situation. War criminals from other conflicts, such as the Yugoslav Wars, have also had their citizenship stripped after their involvement in war crimes became known.

Others have been stripped of their citizenship for more mundane crimes; unless otherwise noteworthy, these people are not included on this list. Some of the people on the list below agreed after legal consultation and/or Department of State communications to give up their United States citizenship/nationality in order to avoid legal prosecution and/or exhaustive deportation/removal proceedings, which does not constitute voluntary relinquishment of citizenship as contrasted with the list of former United States citizens who relinquished their nationality.
