Nationalist Youth of Catalonia (Joventut Nacionalista de Catalunya, JNC) is the youth organisation of Together for Catalonia,[6] founded in 1980 as the youth group of Democratic Convergence of Catalonia (CDC).

Ariadna Urroz is the general secretary since March 2023.

It is a full member organization of the European Liberal Youth and the International Federation of Liberal Youth.

JNC was founded in April 1980 in Platja d'Aro by young members of CDC, and refounded in 2016 as the PDeCAT.

The organization gradually evolved to independentist positions, which also influenced the political orientation of CDC.
