The Youth Party – European Greens (Slovene: Stranka mladih – Zeleni Evrope, SMS-Zeleni) is a green[1] political party in Slovenia.

Until July 2009, it was called Youth Party of Slovenia (Stranka mladih Slovenije, SMS).

At the early 2011 Slovenian parliamentary election on 4 December 2011, the party won 0.86% of the vote, thus not gaining any seat in the National Assembly.

[3] At the parliamentary elections on 3 October 2004, the party won 2.1% of the popular vote and no seats.

Traditionally, the youth in Slovenia have been unresponsive to political issues and though the party strongly encourages young people to get involved it considers itself a party for anyone who desires a fresh and spirited approach to politics in Slovenia.
