Syriza Youth (Greek: Νεολαία ΣΥΡΙΖΑ) is the youth organisation of the Coalition of the Radical Left (Syriza) in Greece. Founded in 2013, it was a member of the European Network of Democratic Young Left (Endyl).

The Syriza Youth was founded when the largely bottom-up structure of Young Syriza (Νέοι–Νέες ΣΥΡΙΖΑ) groups and the Synaspismos Youth united forming a nationwide organisation.

At the founding conference on 19–22 December 2013, 522 delegates of the 128 local groups both in Greece and abroad convened in Kerameikos, Athens. The four-day conference was also attended by a number of Syriza leaders including party secretary Dimitris Vitsas and parliamentary spokesman Panagiotis Kouroumplis.

On 22 December, the delegates ratified the final text of the founding declaration on the first ballot. Inner-organisational tensions however culminated when the "Left Platform" opposed the final text arguing that it lacked a clear political position as a government of the Left should not accept any compromise with its creditors. The "Left Movement" voted blank after their "Charter of the Rights of Youth" had been rejected as an amendment by a majority of the delegates.

The delegates concluded with the election of 67 members of the organisation's first Central Council with the more pragmatic factions winning a clear majority. Four additional members remained to be appointed as honorary members.

By its founding declaration the organisation defines itself as being part of the radical left that participates in the class struggle striving to abolish all kinds of exploitation and aiming at a Socialism of the 21st century. The organisation's manifesto includes ten positions:

Syriza Youth upholds a quota of one third for young women to participate in all organisational bodies.

Apart from branches all over Greece, the Syriza Youth also has a number of international branches in Belgium, France, Germany, the Netherlands, Sweden and the United Kingdom.
