Formula Easter was a single-seater, open wheel, open cockpit circuit car racing series during the 1970–1980s, specifically created for drivers from the communist bloc. Cars driven were created solely from parts manufactured by the COMECON industry or created from scratch as a citizens' initiative by Eastern Bloc residents. Nominally, the series belonged to FIA Formula Category 9 and Technical Group 8, although the FIA only acknowledged, and did not officially sanction, its existence.
