The Medal of the Crown of King Zvonimir (Croatian: Kolajna krune Kralja Zvonimira) was a decoration for military and civil achievements that benefit the Croatian people and the Independent State of Croatia.

Croatian sculptor Ivo Kerdić created the medal, which has three grades: silver, bronze, and iron.

It is named after King Demetrius Zvonimir of Croatia, who ruled during the 11th century and was known for being loyal to the Pope.

Decorations with oak leaves on the obverse signify acts of gallantry in action.

The medal was awarded until May 1945, and was given to several Germans as well as Croatian nationals fighting on the Eastern Front and in the Balkans campaign.
