Sándor Garbai (1879-1947) was a Hungarian socialist politician. He came to power as prime minister in March 1919 in alliance with the Communists, and proclaimed a Soviet Republic. Although Garbai remained titular head of the regime for most of its length, practical authority was in the hands of Communist foreign minister Béla Kún.
