Zsigmond Kunfi (born as Zsigmond Kohn; 28 April 1879 – 18 November 1929) was a Hungarian politician, literary historian, journalist and translator, who served as Minister without portfolio of Croatian Affairs and as Minister of Labour and Welfare between 1918 and 1919.
His political and philosophical views were near to Karl Kautsky's radical ideas.
In 1904, he became member of the Social Democratic Party of Hungary, therefore he lost his job as a grammar school teacher in Kolozsvár.
In 1907 he moved to Budapest, where he became the Deputy Editor-in-Chief of the Népszava ("People's voice") weekly journal and from 1908 he wrote for the Szocializmus magazine, but he also often wrote articles for the Nyugat and the Huszadik század ("20th Century") literary journals.
He held this position also during the Hungarian Soviet Republic as People's Commissar.
