The Anti-Fascist Youth Union of the Free Territory of Trieste (Italian: Unione gioventù antifascista del Territorio libero di Trieste, abbreviated UGA, Slovene: Zveza antifašistične mladine Svobodnega tržaškega ozemlja, abbreviated ZAMSTO), initially known as the Anti-Fascist Youth Union of the Julian March (Italian: Unione gioventù antifascista della Regione Giulia, Slovene: Zveze antifašistične mladine Julijske krajine, abbreviated ZAMJK) was a youth movement in the Julian March (later the Free Territory of Trieste).
The union was formed as a continuation of Italian and Slovenian anti-fascist youth groups in the area by the end of World War II.
It was followed by the founding conference of the Anti-Fascist Youth Union of the Julian March on November 1, 1945, at which the merger of the different groups was completed.
