The International Socialist Organization (ISO) was a Trotskyist group active primarily on college campuses in the United States that was founded in 1976 and dissolved in 2019. The organization held Leninist positions on imperialism and the role of a vanguard party. However, it did not believe that necessary conditions for a revolutionary party in the United States were met; ISO believed that it was preparing the ground for such a party. The organization held a Trotskyist critique of nominally socialist states, which it considered class societies. In contrast, the organization advocated the tradition of "socialism from below." as articulated by Hal Draper. Initially founded as a section of the International Socialist Tendency (IST), it was strongly influenced by the perspectives of Draper and Tony Cliff of the British Socialist Workers Party. It broke from the IST in 2001, but continued to exist as an independent organization for the next eighteen years. The organization advocated independence from the U.S. two-party system and sometimes supported electoral strategies by outside parties, especially the Green Party of the United States.
