Württemberg-Hohenzollern was a West German state created in 1945 as part of the French post-World War II occupation zone.

Württemberg-Hohenzollern should not be confused with the larger Gau ("shire") of the same name that was formed briefly during the Third Reich.

Württemberg-Hohenzollern consisted of the southern half of the former state of Württemberg and the Prussian administrative region of Hohenzollern.

The division between north and south was set so that the Autobahn connecting Karlsruhe and Munich (today the A8) was completely contained within the American zone.

A straw poll was held on 24 September 1950 in Württemberg-Hohenzollern, Württemberg-Baden, and Baden regarding a merger of the three states.
