The Frontier March of Posen-West Prussia (German: Grenzmark Posen-Westpreußen, Polish: Marchia Graniczna Poznańsko-Zachodniopruska) was a province of the Free State of Prussia within the German Weimar Republic. The capital was Schneidemühl (present-day Piła). The province comprised the small western parts of the former Prussian territories of Posen and West Prussia, that remained with Germany after World War I according to the Treaty of Versailles.
The province comprised two spatially separated areas, stretching from the Prussian Province of Pomerania and the "Polish Corridor" in the north along the eastern border of the Province of Brandenburg to the Silesia Province in the south.
The lands had been part of the Greater Poland and East Pomeranian (Pomerelian) regions, which until the late 18th century partitions of Poland had been incorporated into the Poznań and Pomeranian voivodeships of the Polish–Lithuanian Commonwealth. The Kingdom of Prussia had established the West Prussian province on Pomerelian and Greater Polish territories annexed during the 1772 First Partition, followed by the annexation of remaining Greater Poland in the Second Partition of 1793, which ended the existence of the Polish state.
