The Brioni Agreement or Brioni Declaration (, , ) is a document signed by representatives of Slovenia, Croatia and the Socialist Federal Republic of Yugoslavia under the political sponsorship of the European Community (EC) on the Brijuni Islands on 7 July 1991. The agreement sought to create an environment in which further negotiations on the future of Yugoslavia could take place. However, ultimately it isolated the federal prime minister Ante Markovic in his efforts to preserve Yugoslavia, and effectively stopped any form of federal influence over Slovenia. This meant the Yugoslav People's Army (JNA) would focus on combat in Croatia, creating a precedent of redrawing international borders and staking the EC's interest in resolving the Yugoslav crisis.
