Dead Man Walking is a work of non-fiction by Sister Helen Prejean, a Roman Catholic nun and one of the Sisters of Saint Joseph of Medaille. She has become a leading American advocate for the abolition of the death penalty. Her crusade began in New Orleans, Louisiana, in 1981, through a correspondence she maintained with a convicted murderer, Patrick Sonnier, who was sentenced to death by electrocution.

Dead Man Walking is the first opera by Jake Heggie, with a libretto (based on the book by Sister Helen Prejean, CSJ) by Terrence Mc Nally; it was premiered by San Francisco Opera on October 7, 2000, with Susan Graham as Sister Helen, John Packard as Joseph De Rocher, and Frederica von Stade as Mrs. Patrick De Rocher. Patrick Summers conducted the San Francisco Opera Chorus and Orchestra.

"Dead Man Walking" is song and single by David Bowie and Reeves Gabrels from the 1997 album Earthling.
