Průkopník svobody ('Pioneer of Freedom') was a Czech language newspaper published from Vienna, Austria.
The editorial board of Průkopník svobody belonged to the leftwing of the Austrian Social Democracy, and in 1920 the newspaper was identified as pro-Bolshevik in correspondence of the Communist International.
From 1921 onwards, Průkopník svobody was the organ of the Czech communists in the Republic of Austria.
[3] Due to the weakness of the Czech Section of the Communist Party of Austria, the paper was closed down in 1929.
The writer Hugo Sonnenschein (a poet who wrote under the pseudonym 'Brother Sonka') had been a contributor to the paper.
