Bulgaria–Germany relations (Bulgarian: Българо-германски отношения, German: Bulgarisch-deutsche Beziehungen) are foreign relations between Bulgaria and Germany. Bulgaria has an embassy in Berlin, a general-consulate in Munich and an office in Bonn. Germany has an embassy in Sofia. Both countries are members of the European Union and NATO. The Bulgarian government views Germany as its key strategic partner in the EU. Some Bulgarian government ministers and President Plevneliev speak German. German experts have been and still are active in an advisory capacity in Bulgarian government ministries as part of continuing implementation measures connected with the country’s EU accession.
In World War I, the Kingdom of Bulgaria fought alongside the German Empire as a member of the Central Powers and signed in 1915 the initially secret Bulgaria–Germany treaty. In 1941, Bulgaria signed the Tripartite Pact, allying itself with Nazi Germany and the Axis Powers. During the Cold War, the People's Republic of Bulgaria and the German Democratic Republic were both members of the Warsaw Pact alliance, until the Reunification of Germany in 1990.
