Grigore Preoteasa (August 25, 1915 – November 4, 1957) was a Romanian communist activist, journalist, and politician, who served as Communist Romania's Minister of Foreign Affairs between October 4, 1955 and the time of his death.
Selected a member of the Central Committee in December 1955, replacing Leonte Răutu as head of the Propaganda Section, he became secretary of the Central Committee and deputy member of the Politburo in June 1957. He was probably seen by Gheorghe Gheorghiu-Dej as a replacement for Răutu, who was by then falling out of favour.
As minister, Preoteasa was noted for handling the aftermath of the Hungarian Revolution of 1956, and for detaining on Romanian soil those Hungarian politicians who had been captured by the Soviets — including Imre Nagy (kept in a Securitate building in Snagov) and György Lukács. Following a request from János Kadar, Romanian authorities referred to many of these arrests as "granting asylum", implying that the Soviets had extended their protection in the face of counterrevolution. His government office was taken over by Ion Gheorghe Maurer in July 1957.
A member of the PMR delegation to the 40th anniversary of the October Revolution in Moscow (alongside Gheorghiu-Dej, Chivu Stoica, Alexandru Moghioroş, Ştefan Voitec,Nicolae Ceauşescu, and Răutu), Preoteasa died at Vnukovo International Airport, minutes after their Aeroflot aircraft missed the landing field and caught fire. According to witnesses, Preoteasa was the only person standing at the time, telling others that he was glad not to have been asked to wear a seat belt; when control of the airplane was lost, he remarked, probably in jest, "This was not in the schedule", which were to be his last words.
Recurring speculations that the incident had been specifically designed to kill Preoteasa, or that it was meant by the Soviets for Gheorghiu-Dej as relations between the latter and Nikita Khrushchev had soured dramatically, are contradicted by the fact that Ceauşescu, Răutu, and other passengers all sustained serious injuries while the Soviet crew was killed. Commentators tend to agree that his death did facilitate Ceauşescu's maneuvering for power after 1964.
