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

During World War II, Yugoslavia was invaded by the Axis forces in April 1941 and the Nazi-allied Independent State of Croatia began a genocidal campaign against Serbs, Jews and Roma, setting up numerous concentration camps in Croatia. After she learned about children held at the camp Lobor-Grad, in October 1941, together with a number of co-workers, in particular Marko Vidaković and Đuro Vukosavljević, she launched a relief campaign named "Action Diana Budisavljević". The Action took care of mostly Serbian children but also women held in various concentration camps including the Jasenovac death camps.

The operation succeeded in saving around 10,000 children. Budisavljević described the course of the Action in a diary, starting with 23 October 1941 and the final entry on 7 February 1947.
