Hungary–Russia relations refer to bilateral foreign relations between the two countries, Hungary and Russia. After the Second World War, Hungary and the Soviet Union became economic and military allies; both were signatories of the Warsaw Pact. The relations between both countries were damaged in 1956 due to the Soviet intervention in the revolution occurring in Hungary. However both countries reastablished diplomatic relations after the breakup of the USSR. Both countries are full members of the Council of Europe and the Organization for Security and Co-operation in Europe.
