The Oder (German pronunciation: [ˈoːdɐ]; Czech, Lower Sorbian and Polish: Odra, Upper Sorbian: Wódra) is a river in Central Europe. It rises in the Czech Republic and flows (generally north- and northwest-ward) through western Poland, later forming 187 kilometres (116 mi) of the border between Poland and Germany, part of the Oder–Neisse line. The river ultimately flows into the Szczecin Lagoon north of Szczecin and then into three branches (the Dziwna, Świna and Peene) that empty into the Gulf of Pomerania of the Baltic Sea.

The Oder is known by several names in different languages, but the modern ones are very similar: English and German: Oder; Czech, Polish, and Lower Sorbian: Odra, Upper Sorbian: Wódra; Kashubian: Òdra (pronounced [ˈwɛdra]); Medieval Latin: Od(d)era; Renaissance Latin: Viadrus (invented in 1534).

Ptolemy knew the modern Oder as the Συήβος (Suebos; Latin Suevus) – a name apparently derived from the Suebi, a Germanic people. While he also refers to an outlet in the area as the Οὐιαδούα Ouiadoua (or Οὐιλδούα Ouildoua; Latin Viadua or Vildua), this was apparently the modern Wieprz, as it was said to be a third of the distance between the Suebos and Vistula. The name Suebos may be preserved in the modern name of the Świna river (German Swine) – an outlet from the Szczecin Lagoon to the Baltic.
