The Hartheim Euthanasia Centre () was a killing centre that Nazi Germany used to kill people with disabilities during World War II. The Nazis' ideas about eugenics said that people with disabilities were "life unworthy of life. Hartheim was one of six "euthanasia centres" the Nazis set up for their T4 Euthanasia Programme. Their goal was to get rid of all of Germany's people with disabilities. The killing centre was housed in Hartheim Castle in Alkoven, near Linz, Austria.
