Sotsyalistishe Kinder Farband

The Sotsyalistishe Kinder Farband or SKIF ('Socialist Children's Union', S.K.I.F.) was founded in Eastern Europe as the youth organisation of the Jewish Labour Bund, a Jewish Socialist political party. S.K.I.F has three core ideological principles: Chavershaft ("camaraderie", equality and empathy), Doikayt ("Being here", Jews should live, build their culture and struggle for their rights wherever they dwell, rather than seeking refuge in a Jewish homeland), and Yiddishkeit (Jewish identity through Jewish and Yiddish culture). The plural form of a SKIF member is Skifistn and the leaders who run skif are the Helfers, aged 18-20.

The S.K.I.F. in Poland is now defunct.Melbourne S.K.I.F established itself in 1950. Melbourne SKIF, is one of the last remaining SKIF branches, subsequently it is usually regarded as the SKIF organization itself. However, the SKIF in France didn't disband, but in 1963 changed its name to , CLEJ.
