Géza Losonczy (5 May 1917, Érsekcsanád – 21 December 1957) was a Hungarian journalist and politician.
During the 1956 Hungarian revolution, he joined the Imre Nagy government as minister of press and propaganda affairs.
He and Zoltán Tildy held the government's last press conference on 3 November.
On 4 November, as the Soviet army poured into Budapest, he took refuge in the Yugoslavia Embassy, and on 22 November he and the other members of the Imre Nagy group were arrested and transported to Romania.
While in captivity, awaiting trial for treason, Losonczy went on hunger strike.
