Captain Yevgeny Mikhailovich Ivanov (; 11 January 1926 – 17 January 1994), also known as Eugene Ivanov, was a naval attaché at the Soviet Embassy in London during the early 1960s, and was also engaged in espionage. His affair with Christine Keeler resulted in another of her lovers, John Profumo, resigning from the United Kingdom government, in what became known as the Profumo affair.
