Diana Budisavljević (née Obexer; 15 January 1891 – 20 August 1978) was an Austrian humanitarian who led a major relief effort in Yugoslavia during World War II.

After she learned about children held at Loborgrad concentration camp, she launched a relief campaign in October 1941 named "Action Diana Budisavljević" along with a number of co-workers, in particular Marko Vidaković and Đuro Vukosavljević.

During that work, in March 1942, Budisavljević met the head nurse, Dragica Habazin, who became a close collaborator in the following months and years in helping the inmates from various camps that were relocated to Zagreb and other places.

[8] At the beginning of July 1942, with assistance from German officer Gustav von Koczian,[9] she obtained written permission to remove children from the Stara Gradiška concentration camp [8] and with the help of the Ministry of Social Affairs, in particular Professor Kamilo Bresler, she was able to transport the former child prisoners to Zagreb, Jastrebarsko and later also to Sisak.

[10] After the rescue efforts in Stara Gradiška, Budisavljević, wearing a Red Cross nurse's uniform, oversaw the transport of children out of Mlaka, Jablanac and Košutarica camps.

[1] At the request of Kamilo Bresler in August 1942, she and Ivanka Džakula, along with some other co-workers, started to compile file-card information on children, based on transportation lists and sources from various institutions that retained their own files.

Upon a signed request on 28 May 1945 by a Federal State of Croatia official named Tatjana Marinić, at that time Head of Ministry of Social Affairs, Budisavljević handed over the file-cards to the government.

[5] On 15 February 2012, at the Serbian Statehood Day, the President of the Republic Boris Tadić posthumously decorated Diana Budisavljević with the Golden Medal of Miloš Obilić for courage and personal heroism.
