Obóz Narodowo-Radykalny (National Radical Camp, ONR) was a Polish nationalist political party, formed on May 14, 1934 mostly by the youth radicals who left the Narodowa Demokracja movement.

The party was created on the insistance of former members of the Obóz Wielkiej Polski , most notably Jan Mosdorf , Tadeusz Gluziński and Henryk Rossman . The organisation was mostly secred and followed the fascist ideology. It supported class solidarity , nationalisation of foreign and especially Jewish-owned companies and introduction of anti-semitic laws. It also supported defence of private property and a centralised state.

The ONR was popular mostly among the students and other groups of urban youth. Because of its involvement in boycott of Jewish-owned companies, as well as numerous attacks on left-wing worker demonstrations, the ONR was delegalised in July 1934. It continued to act clandestinely. In 1935 it broke onto two separate factions: the ONR Falanga and the A.B.C. group.

During World War II both organisations created underground resistance organisations: the earlier was transformed into the Związek Jaszczurczy and Szaniec , while the latter created the Konfederacja Narodu .
