Nicholas Daniloff (born 1934) is an American journalist who graduated from Harvard University and was most prominent in the 1980s for his reporting on the Soviet Union. He came to wider international attention on September 2, 1986 when he was arrested in Moscow by the KGB and accused of espionage.
The Reagan administration took the position that the Soviets had arrested Daniloff without cause, in retaliation for the arrest three days earlier of Gennadi Zakharov, an employee of the Soviet UN Mission. The Soviets initially contended that Daniloff had confidential government documents on him when he was arrested.
After intense discussion between the governments, on September 23 Daniloff was allowed to leave the Soviet Union without charges, Zakharov was allowed to leave the U.S. after pleading nolo contendere, and Soviet dissident Yuri Orlov was released to the West.
