Dezinformatsia: Active Measures in Soviet Strategy is a non-fiction book about disinformation and information warfare used by the KGB during the Soviet Union period, as part of their active measures tactics. The book was co-authored by Richard H. Shultz, professor of international politics at Tufts University, and Roy Godson, professor emeritus of government at Georgetown University.

Disinformation is false information deliberately spread to deceive people. Disinformation is an orchestrated adversarial activity in which actors employ strategic deceptions and media manipulation tactics to advance political, military, or commercial goals. Disinformation is implemented through attacks that "weaponize multiple rhetorical strategies and forms of knowing—including not only falsehoods but also truths, half-truths, and value judgements—to exploit and amplify culture wars and other identity-driven controversies."
