The Oder–Neisse line is an unofficial term for the modern border between Germany and Poland. The line generally follows the Oder and Lusatian Neisse rivers, meeting the Baltic Sea in the north. A small portion of Polish territory does fall west of the line, including the cities of Szczecin and Świnoujście.

The Germany–Poland border is the state border between Poland and Germany, mostly along the Oder–Neisse line, with a total length of 467 km (290 mi). It stretches from the Baltic Sea in the north to the Czech Republic in the south.
