National Radical Camp Falanga (Polish: Obóz Narodowo-Radykalny Falanga, ONR-Falanga) was a Polish political group. It was one of two groups to emerge following the banning of the National Radical Camp in 1934.

The ONR-Falanga was formed in 1934 following a split by members of the National Radical Camp held in Detention Camp Bereza Kartuska. Adopting the name of Ruch Narodowo-Radykalny (National Political Movement), it soon became known as Falanga as that was the name of its journal (the same thing happening to the rival group, which was known as National Radical Camp ABC).

The group was led by Bolesław Piasecki and advocated a 'Catholic totalitarianism' inspired by Falangism. However, although clearly derived from Falangism, it has been argued that their Catholicism was even more central than that of the Spanish group and indeed their pronouncment that 'God is the highest form of man' recalled the religious fanaticism of Corneliu Zelea Codreanu. The group is widely considered to have been a fascist movement.

The National Radical Camp (Polish: Obóz Narodowo Radykalny, ONR) was a Polish extreme rightanti-semitic,anti-communist, and nationalist political party, formed on 14 April 1934 mostly by the youth radicals who left the National Party of the National Democracy movement.

The party was created on the insistence of former members of the Camp of Great Poland (Obóz Wielkiej Polski), most notably Jan Mosdorf, Tadeusz Gluziński and Henryk Rossman. The organisation proclaimed changes in the government based on the nationalist ideology. It supported class solidarity, nationalisation of foreign and Jewish-owned companies and introduction of anti-semitic laws. At the same time it supported defence of private property and a centralised state. The leading members of ONR-ABC included Henryk Rossman, Tadeusz Gluziński, Stanisław Piasecki, Jan Jodzewicz, Wojciech Zaleski, Tadeusz Todtleben and Jan Korolec. The leading members of ONR-Falanga included Bolesław Piasecki, Wojciech Wasiutyński, Wojciech Kwasieborski and Marian Reutt.
