Vladimir Ippolitovich Vetrov (Russian: Владимир Ипполитович Ветров; 10 October 1932 – 23 January 1985) was a high-ranking KGB spy during the Cold War who decided to covertly release valuable information to France and NATO on the Soviet Union's clandestine program aimed at stealing technology from the West. His history inspired the book Bonjour Farewell: La Vérité sur la Taupe Française du KGB (1997) by Sergei Kostin. It was loosely adapted for the French film L'affaire Farewell (2009), starring Emir Kusturica, Guillaume Canet and Alexandra Maria Lara.
