Polish Corridor
- a former region of Poland which extended northwards to the Baltic coast and separated East Prussia from the rest of Germany, granted to Poland after the First World War to ensure Polish access to the coast. Its annexation by Germany in 1939, with the German occupation of the rest of Poland, precipitated the Second World War. After the war the area was restored to Poland.波兰走廊（原波兰一地区, 向北延伸至波罗的海海岸, 将东普鲁士和德国其余地区分隔开来, 一战后割给波兰以使其有出海口; 1939年德国并吞了这一地区, 并占领了波兰其余领土, 从而促使了二战的爆发; 二战后, 该地区归还波兰）。
