Batzarre (English: Assembly) is a political party in Navarre, Spain.
It bids to win the political space to the left of the Basque nationalists and the Spanish socialists, the latter eroded for their long-running collusion with the conservative UPN government.
It formed on 29 January 2011 the coalition Izquierda-Ezkerra along with Izquierda Unida de Navarra (IUN) and local Socialist figures disillusioned with the party's regional alliances.
It formed out of the merger of EMK and LKI, the Basque branch of LCR.
In 1998, the party was one of the members of Euskal Herritarrok; however, it left the coalition after ETA broke the 1998 truce.
