The Territorial Prelature of Schneidemühl (German: Freie Prälatur Schneidemühl, Latin: Territorialis Praelatura Schneidemuhlensis, Polish: Niezależna Prałatura Pilska) was a Roman Catholic territorial prelature in first Germany (Nazi Germany as of 1933) and then Poland. It was located first in the Prussian Province of the Frontier March of Posen-West Prussia, but also including the Pomeranian Lauenburg and Bütow Land. It was named after its seat in Schneidemühl (Piła) and belonged to the Eastern German Ecclesiastical Province under the Breslau Metropolia since 1930.

Parts of the newly Polish bishoprics of the Archdiocese of Gniezno-Poznań (until 1946 in personal union) and the Diocese of Culm remained with Germany after the boundary changes in 1919 and 1920 following World War I. On 1 December 1920 Archbishop Edmund Dalbor of Gniezno-Poznań appointed an archiepiscopal delegate with the powers of a vicar general for the five concerned deaneries with 45 parishes and 80,000-100,000 Catholic faithful. Bishop Augustinus Rosentreter of Culm again refused to separate his three concerned deaneries located in the eastern Pomeranian districts of Bütow (Bytow) and Lauenburg in Pomerania (Lębork) and southwestern West Prussia with about 40,000 Catholic parishioners.
