Margaret Pabst Battin, also known as Peggy Battin, is an American philosopher, medical ethicist, author, and a current Distinguished Professor at the University of Utah. She is a supporter of assisted dying and has worked extensively on ethical aspects of this issue. In 1993, she was named a Spinoza Chair at the University of Amsterdam for her studies on assisted dying. Battin is a Hastings Center Fellow. In 2008 Battin's husband became quadriplegic after a bicycle accident, which caused her to refine and augment her thinking about assisted dying; he died in 2013 after he requested to turn off his life support.
