Yugoslav Committee (, ) was a political interest group formed by South Slavs from Austria-Hungary during World War I aimed at joining the existing south Slavic nations in an independent state. Founding members included: Frano Supilo Ante Trumbić Ivan Meštrović Hinko Hinković Franko Potočnjak Nikola Stojanović Dušan Vasiljević First three members were Croats from Kingdom of Dalmatia, next two members were Croats from Kingdom of Croatia -Slavonia, while the last two were Serbs from Bosnia and Herzegovina. Their initial gathering happened in 1914 while the committee was officially formed on 30 April 1915 in the Parisian Hotel Madisson. As Britain was the leader of the Entente, London was chosen as the headquarters of the Committee. The president was Ante Trumbić. In 1915, there were 17 members in the Committee, of which 11 from the Croatian and Dalmatian littoral regions. During that year, the Committee formed branches in Paris, Geneva, St. Peterburg, Cleveland, Valparaiso and Washington.

However, they could not come to an agreement on that issue, and Frano Supilo left the Yugoslav Committee on 5 June 1916. He died the following year. The committee signed the Corfu Declaration with the Kingdom of Serbia in 1917. It was a compromise declaration, advocating a parliamentary monarchy, with three nations and two alphabets equal before the law, religious freedom and universal suffrage. It received political sponsorship of Great Britain and France. In October 1918, the State of Slovenes, Croats and Serbs was declared from the liberated lands from the Austro-Hungarian Empire in what would become the first incarnation of a Yugoslav state. This did not achieve recognition. In December, the State united with the Kingdom of Serbia (which had just expanded its borders after World War
