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 Versailes.
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.
After the Napoleonic Wars and the Congress of Vienna in 1815, Prussia maintained the acquired lands, that however still laid beyond the borders of the German Confederation. Their population was predominantly Catholic and Polish-speaking, while a sizable Protestant German minority settled mainly in the western parts. The annexed lands were internally re-arranged within the West Prussia Province and the Greater Polish Grand Duchy of Posen, which finally lost its semi–autonomous status after the failed Greater Poland Uprising of 1848. With Prussia, these provinces became part of the unified German Empire in 1871. Ethnic tensions were exacerbated by the Germanisation policies of the Berlin government and the anti-Catholic Kulturkampf measures enacted by Chancellor Otto von Bismarck.
Upon the German defeat in World War I, another Greater Poland Uprising broke out in 1918, which aimed to incorporate the lands once annexed by Prussia into a re-established Polish state. The forces of the Polish Military Organisation were able to oust the German administration from the bulk of the Greater Polish lands, whereafter the Posen governor (Landeshauptmann) Ernst von Heyking was forced to retire to Meseritz (Międzyrzecz) and de facto only ruled over the far western, predominantly German settled districts at the border with the adjacent Prussian provinces of Pomerania, Brandenburg and Silesia.
The Polish advance was halted, after the German forces had re-organised in several Freikorps units, and the demarcation line became the basis of the ruling by the 1919 Treaty of Versailles, adjudicating the parts occupied by Polish forces uti possidetis to the Second Polish Republic. The governmental power of the German administration was confined to the smaller western parts of Posen and West Prussia, the Prussian state government was represented by the former Bromberg supervisor (Regierungspräsident) Friedrich von Bülow, who relocated his administrative seat to Schneidemühl. With the entry into force of the German Ostmark[disambiguation needed] law on 1 July 1922, the province was created out of those smaller western parts of former Posen and West Prussia that remained with the Weimar Republic.
In view of the previous clashes of arms and the "lost" territories, the remaining German population from the beginning had a strong nationalistic attitude, with the national conservative German National People's Party (DNVP) emerging as the strongest political power in the provincial elections. Friedrich von Bülow, himself a member of the national liberal German People's Party, remained Oberpräsident until his retirement in 1933, whereafter he was succeeded by the Meseritz DNVP politician Hans von Meibom. After the DNVP dissolved in the course of the Nazi Gleichschaltung process, von Meibom was disempowered and replaced by the Nazi Oberpräsident of neighbouring Brandenburg, Wilhelm Kube. Kube, notorious for his corruption, ruled over both provinces until he was deposed after entering into a conflict with the Nazi jurist Walter Buch, father-in-law of mighty Martin Bormann. Posen-West Prussia was further on ruled with Brandenburg under Nazi Oberpräsident Emil Stürtz until it was dissolved in 1938, when its territory was divided between the adjacent provinces of Silesia, Pomerania and Brandenburg.
Despite the name, the city of Posen, Polish: Poznań, was no longer part of the province, as it had become the capital of the re-established Greater Polish Poznań Voivodeship of the Second Polish Republic. The capital of the Prussian Posen-Westpreußen province and seat of the Oberpräsident supervisor was Schneidemühl. The seat of the province's Landeshauptmann elected by the Landtag assembly remained at Meseritz.

The office of an Oberpräsident appointed by the Prussian state government had to carry out central prerogatives on the provincial level and to supervise the implementation of central policy on the lower levels of administration. The urban and rural districts elected representatives for the provincial diet (Provinziallandtag). This parliament legislated within the competences transferred to the province. The diet of Posen–West Prussia elected a provincial executive body (government), the provincial committee (Provinzialausschuss), and the Landeshauptmann as head of the province.
