The Polabian language, also known as Drevanian–Polabian language, Drevanian language, and Lüneburg Wendish language, is a West Slavic language that was spoken by the Polabian Slavs in present-day northeastern Germany around the Elbe. It was spoken approximately until the rise to power of Prussia in the mid-18th century – when it was superseded by Low German – in the areas of Pomoré, central (Mittelmark) part of Branibor (Brandenburg) and eastern Saxony-Anhalt, as well as in eastern parts of Wendland and Dravänia (Schleswig-Holstein), Ostholstein and Lauenburg). Polabian was also relatively long spoken in and around the cities of Bukovéc (Lübeck), Starigard (Oldenburg) and Trava (Hamburg). The very poorly attested Slavic dialects of Rügen seemed to have had more in common with Polabian than with Pomeranian varieties. In the south, it bordered on the Sorbian language area in Lusatia.

The West Slavic languages are a subdivision of the Slavic language group. They include Polish, Czech, Slovak, Kashubian, Upper Sorbian and Lower Sorbian. The languages have traditionally been spoken across a mostly continuous region encompassing the Czech Republic, Slovakia, Poland, the westernmost regions of Ukraine and Belarus, and a bit of eastern Lithuania. In addition, there are several language islands such as the Sorbian areas in Lusatia in Germany, and Slovak areas in Hungary and elsewhere.
