European Nation State (in Spanish: Estado Nacional Europeo), also referred to as N, is a small far-right political party in Catalonia, Spain.

The party defines itself as "National European" and "Popular Socialist".

In the latter, the party received 410 votes.

In October 2005 police arrested six N members, including the party general secretary Luis Antonio García Rodríguez.

The Fiscalia del Tribunal Superior de Justícia de Catalunya has petitioned that N ought to be banned on the grounds of being a Nazi party.
