Breton Liberty (Breton: Frankiz Breizh, French: Liberté Bretagne) was a leftist national liberation movement in Brittany, France. It split off from the Breton Democratic Union, though the two parties' political stances were similar. Breton Liberty frequently worked within the Région et Peuples Solidaires federation. Its activities were limited to the regions of Brest and Léon and during its last years it did not have more than a dozen active member. The party was dissolved in 2007, and some of its members joined the Breton Democratic Union.
