Kreis Hohensalza ([ˌhoːənˈzalt͡sa]) was one of many Kreise (districts) in the northern administrative region of Bromberg, in the Prussian province of Posen from 1815 to 1919.
The capital city, formerly known as Inowrazlaw, was renamed Hohensalza on 5 December 1904, and the county name also changed by default.
Following the Treaty of Versailles in July 1919, Germany also ceded the northern part of the district to Poland between 17 January and 4 February 1920.
During World War II, the territory of the former Kreis was annexed by Nazi Germany and Landkreis Hohensalza (Wartheland) was established, which existed from 1939 to 1945.
In addition, the following cities were separate districts for urban residents: Hohensalza, Argenau.
