Russ Bellant (born 1949) is an American journalist, political activist, and author. He was an Associate of Political Research Associates.

Old Nazis, the New Right, and the Republican Party is Bellant's most widely cited work. Chris Simpson wrote in the preface, "This book presents some of the best new research into the seamy side of the 'Reagan Revolution.' Russ Bellant's careful dissection of the American Security Council Foundation and of certain Republican Party organizations clearly establishes that neo-fascist thinking is flourishing among some of the right-wing activists who today drape themselves in the American flag."^{[1][third-party source needed]}

The Harvard Educational Review calls Old Nazis, the New Right, and the Republican Party an important book "which exposes the roots and growth of domestic fascist networks."^[2] Bellant interviewed Nikolai Nazarenko of the Cossack American Republican National Federation who proved all too willing to show his collection of Nazi memorabilia and anti-Semitic literature.^{[3][third-party source needed]}

In the same book Bellant documents Nazi involvement in the Ukraine; The Nation said "Bellant's exposure of émigré Nazi leaders from Germany's World War II allies in the 1988 Bush presidential campaign was the driving force in the announced resignation of nine individuals, two of them from Ukraine".^[4] Former Office of Special Investigations director Allan A. Ryan called it, "Well-documented, and reliable."^{[third-party source needed]}

Organizations dedicated to countering Holocaust denial such as The Nizkor Project frequently cite Bellant's work.^{[5][third-party source needed]}

Bellant appeared as himself in the political documentary American Secrets.^[6]
