The Pirate Party Berlin is the state chapter of the Pirate Party Germany in the city-state of Berlin and was the first chapter of the Pirates to enter a Landtag, getting elected to the Abgeordnetenhaus of Berlin in 2011. The party divides itself into so-called Crews at the local level. Work groups on specific themes are called Squads. Since 2010, the national association has used the software LiquidFeedback for intra-party decision-making.

The Abgeordnetenhaus of Berlin is the state parliament (Landtag) of Berlin, Germany according to the city-state's constitution.
