The International Union of Socialist Youth (IUSY) is an international youth labour organization, whose activities include publications, supporting member organizations and organization of meetings. Originally named the Socialist Youth International, the union was formed at the 1907 International Socialist Congress at Stuttgart as the youth wing of the Second International.^[1]

IUSY claims to have 145 member organizations, including 122 full members and 23 observer members, from 106 countries. IUSY gained prominence as an international youth non-governmental organization (NGO) with UN ECOSOC consultative status in 1993.^[2]
