Abertzaleen Batasuna (AB; English: Patriot's Union or Unity) is a Basque political party in France.

[citation needed] Its immediate goal is the establishment of a Pays Basque département out of Pyrénées-Atlantiques.

In terms of ideology, besides Basque nationalism, it is a leftist political party.

[1] In 2001, members of AB who desired a stronger link to Southern Basques left to form the Northern branch of Batasuna, a different party with a similar ideology which is now illegal in Spain.

AB neither justifies nor condemns the violence of ETA, calling instead for a truce.
