The table below lists the Croatian military losses during the war, covering the period between 10 Apr 1941 and 8 May 1945.

It should be noted that it is the wartime Croatia (Nezavisna Drzava Hrvatska, NDH), meaning the territory of today's Republic of Croatia minus Istria, Dalmatia and Baranja, plus Bosnia-Herzegovina and Eastern Sirmium with Zemun, not the present day borders.

Croatian Armed Forces and militia 122.000
Croatian soldiers in German and Italian forces 14.000
Total 136.000
