Danube Banovina or Danube Banate (separator=" / "|Dunavska banovina|Дунавска бановина), was a banovina (or province) of the Kingdom of Yugoslavia between 1929 and 1941. This province consisted of the geographical regions of Syrmia, Bačka, Banat, Baranya, Šumadija, and Braničevo. The capital city of the Danube Banovina was Novi Sad. The province was named after the Danube River.

In 1939, when the new Banovina of Croatia was formed, Šid and Ilok districts were transferred from the Danube Banovina to that of Croatia.
In 1941, the World War II Axis Powers occupied the Danube Banovina. Bačka and Baranja regions were attached to Hungary, while Syrmia was attached to the Independent State of Croatia. The remainder of the former Danube Banovina (including Banat, Šumadija, and Braničevo) were part of the Territory of the Military Commander in Serbia.

In 1945 the region was restored as a province of Serbia within a federal Socialist Yugoslavia. The province was officially renamed as Vojvodina, its historical name, with the capital at the city of Novi Sad. The new province consisted of Syrmia, Banat and Bačka regions. Baranja was included in the People's Republic of Croatia, while Šumadija and Braničevo were included in Serbia Proper.
