The Kingdom of Croatia-Slavonia (; ; ) was a nominally autonomous kingdom and constitutionally defined separate political nation within the Austro-Hungarian Empire, created in 1868 by merging the kingdoms of Croatia and Slavonia following the Croatian–Hungarian Settlement of 1868.

The city of Rijeka, following a disputed section in the 1868 Settlement known as the , became a "corpus separatum" and was legally owned by Hungary, but administrated by both Croatia and Hungary.
