Sfarmă-Piatră (literally "Stone-Crusher" or "Rock-Breaker", named after one of the Uriași characters in Romanian folklore; Romanian pronunciation: [ˌsfarmə ˈpjatrə]) was an antisemitic daily, monthly and later weekly newspaper, published in Romania during the late 1930s and early 1940s. One in a series of publications founded by Nichifor Crainic (better known as the head of Gândirea magazine), with support from Universul editor-in-chief Stelian Popescu, it attempted to regroup the various fascist and pro-fascist movements around Crainic's "ethnocratic" principle. The editorial staff comprised a group of far right intellectuals; alongside the editor-in-chief Alexandru Gregorian, they included Ovidiu Papadima, Vintilă Horia, Dan Botta, Dragoș Protopopescu, Toma Vlădescu, and Pan M. Vizirescu. It notably hosted contributions by writers Ioan Alexandru Brătescu-Voinești, Radu Gyr and Ștefan Baciu.
Noted for its contemptuous style of journalism and its recourse to violent language, Sfarmă-Piatră launched press campaigns against various figures who advocated left-wing or centrist positions, as well as against prominent members of the Jewish-Romanian community. Among the targets of its attacks were mainstream politicians such as Constantin Argetoianu and Constantin Stere, and the well-known writers Tudor Arghezi, Eugen Lovinescu and Mihail Sadoveanu. The publication was involved in a lengthy conflict with left-wing newspapers such as Adevărul and Dimineața, as well as with two rival voices on the far right—the National Christian Party (PNC) of Octavian Goga and A. C. Cuza, and Mihail Manoilescu's Buna Vestire.
