The Province of West Prussia was a province of Prussia from 1773 to 1829 and 1878 to 1920. West Prussia was established as a province of the Kingdom of Prussia in 1773, formed from Royal Prussia of the Polish–Lithuanian Commonwealth annexed in the First Partition of Poland. West Prussia was dissolved in 1829 and merged with East Prussia to form the Province of Prussia, but was re-established in 1878 when the merger was reversed and became part of the German Empire. From 1918, West Prussia was a province of the Free State of Prussia within Weimar Germany, losing most of its territory to the Second Polish Republic and the Free City of Danzig in the Treaty of Versailles. West Prussia was dissolved in 1920, and its remaining western territory was merged with Posen to form Posen-West Prussia, and its eastern territory merged with East Prussia as the Region of West Prussia district.

The Kingdom of Prussia constituted the German state of Prussia between 1701 and 1918. It was the driving force behind the unification of Germany in 1866 and was the leading state of the German Empire until its dissolution in 1918. Although it took its name from the region called Prussia, it was based in the Margraviate of Brandenburg. Its capital was Berlin.
