The Polish Corridor (German: Polnischer Korridor; Polish: Pomorze, Polski Korytarz), also known as the Danzig Corridor, Corridor to the Sea or Gdańsk Corridor, was a territory located in the region of Pomerelia (Pomeranian Voivodeship, eastern Pomerania, formerly part of West Prussia), which provided the Second Republic of Poland (1920–1939) with access to the Baltic Sea, thus dividing the bulk of Weimar Germany from the province of East Prussia. At its narrowest point, the Polish territory was just 30 km wide.^[1] The Free City of Danzig (now the Polish cities of Gdańsk, Sopot and the surrounding areas), situated to the east of the corridor, was a semi-independent German speaking city-state forming part of neither Germany nor Poland, though united with the latter through an imposed union covering customs, mail, foreign policy, railways as well as defence.

A similar territory, also occasionally referred to as a corridor, was originally connected to the Polish Crown until 1308, and was later reclaimed as part of Royal Prussia during the period 1466–1772.^[2]^[3]
