Michael German is a retired American FBI agent, scholar, and writer.

He is a fellow in the Brennan Center for Justice's Liberty and National Security program.

During his 16-year career as a Special Agent in the FBI, German spent many months undercover, first among white supremacists and then among right-wing militants.

German left the FBI in 2004 as a whistleblower, alleging misconduct and mismanagement in counterterrorism cases.

German joined writer and director Daniel Ragussis in creating the screenplay for Imperium, starring Daniel Radcliffe as an undercover FBI Special Agent under an FBI case agent played by Toni Collette.
