Kreis Meseritz (Landkreis Meseritz as of 1939; Polish: Powiat międzyrzecki) was a district in Prussia, first in the southern administrative Region of Posen within the Prussian Province of Posen (till 1920), then within the Province of the Frontier March of Posen-West Prussia (till 1 October 1938) and at last as part of the administrative Region of Frankfurt within the Province of Brandenburg (till 1945). Its former territory presently lies in the eastern part of the Lubuskie Voivodeship, a region of Poland, roughly resembling the extent of the present county Powiat międzyrzecki.

When the area later forming the territory of the Kreis Meseritz was first annexed to Prussia from 1793 to 1807 it formed the Meseritzer Kreis (Meseritz district) within the Province of South Prussia, then governed by the Departement der Kriegs- und Domänen-Kammer zu Posen (Department of the chamber of war and domains at Posen).
After being part of the Duchy of Warsaw the area returned to Prussia as a result of the Congress of Vienna. The Kreis Meseritz came into existence on 1 January 1818 after separation from Kreis Birnbaum. In 1837 it measured 21.78 Prussian square miles (1,292.5 square kilometres (499.0 sq mi)). It consisted mostly of the rural territories around the town of Meseritz. It became part of the North German Confederation in 1867 and of the German Empire when it was founded in 1871.
After World War I, the administration had to be reorganised because the Region of Posen was split. Thus the eastern part of the county was handed over to Poland in 1920, according to the Versailles treaty. In 1920, the remaining county, measuring 706.49 square kilometres (272.78 sq mi), joined the newly founded Regierungsbezirk Schneidemühl, which became part of the Province of the Frontier March of Posen-West Prussia, established in 1922. Together with Kreis Bomst and Kreis Schwerin the Kreis Meseritz formed a western territorial exclave of Posen-West Prussia. When that province was dissolved in 1938 the bulk of its territory, anyway neighbouring Pomerania, was merged into that province, whereas its western exclave became part of the Province of Brandenburg. In 1945, the Landkreis Meseritz was occupied by the Red Army and integrated into Poland.
