Civic Defence (Czech: Občanská obrana) was a Czech paramilitary organisation active on the territory of Cieszyn Silesia during the so-called plebiscite period of the Polish–Czechoslovak dispute over Cieszyn Silesia (1919–1920).
The Civic Defence was created based on the system of the so-called fives: in each municipality there was one trustee who directed five persons he selected.
