The United Panhellenic Organization of Youth, abbreviated EPON (), was a Greek resistance organization that was active during the Axis Occupation of Greece in World War II. EPON was the youth wing of the National Liberation Front (EAM) organization, and was established on 23 February 1943 after the merger of ten earlier political and resistance youth organizations. Along with EAM and its other affiliates, EPON was dissolved judicially at the beginning of the Greek Civil War but continued to operate illegally until 1958.
