John D. Guandolo (born 1965 or 1966) is an American former Federal Bureau of Investigation Special Agent and counterterrorism activist who has provided training seminars for law enforcement and local elected officials across the United States. Having been described as an anti-Muslim conspiracy theorist, his seminars have been controversial and protested against by advocacy groups. He ran the seminars with the organization Understanding the Threat until the group closed down in 2023.
