Indonesia–Yugoslavia relations were historical foreign relations between now split-up Socialist Federal Republic of Yugoslavia and Indonesia. Both countries were founding member states of the Non-Aligned Movement. Two countries established formal diplomatic relations in 1954. First diplomatic documents were exchanged as early as 1947. Breakup of Yugoslavia, one of the founding and core members of the Non-Aligned Movement, brought into question the very existence of the Movement which was preserved only by politically pragmatic chairmanship of Indonesia.
