Mecklenburg-Vorpommern (MV; German: [ˌmeːklənbʊʁkˈfoːɐ̯pɔmɐn] or [ˌmɛk-] (listen); Low German: Mäkelborg-Vörpommern), also known by its anglicized name Mecklenburg–Western Pomerania, is a state in the north-east of Germany. Of the country's sixteen states, Mecklenburg-Vorpommern ranks 14th in population; it covers an area of 23,213 km² (8,963 sq mi), making it the sixth largest German state in area; and it is 16th in population density. Schwerin is the state capital and Rostock is the largest city. Other major cities include Neubrandenburg, Stralsund, Greifswald, Wismar, and Güstrow. It was named after the 2 regions of Mecklenburg and Vorpommern (which means West Pomerania).

The state was established in 1945 after World War II through the merger of the historic regions of Mecklenburg and the Prussian Western Pomerania by the Soviet military administration in Allied-occupied Germany. It became part of the German Democratic Republic in 1949, but was dissolved in 1952 during administrative reforms and its territory divided into the districts of Rostock, Schwerin, and Neubrandenburg. A state called in German Mecklenburg-Vorpommern was re-established in 1990 following German reunification and became one of the new states of the Federal Republic of Germany.

On the state's coastline on the Baltic Sea are many holiday resorts and much unspoilt nature, including the islands of Rügen, Usedom, and others, as well as the Mecklenburg Lake District, making the state one of Germany's leading tourist destinations. Three of Germany's fourteen national parks, as well as several hundred nature conservation areas, are in the state. The University of Rostock, founded in 1419, and the University of Greifswald, established in 1456, are among the oldest universities in Europe. In 2007, the 33rd G8 summit took place at the Grand Hotel Heiligendamm on the Mecklenburg Baltic coast during the chancellorship of Angela Merkel, a native of Mecklenburg-Vorpommern.
