Nellie May Madison (née Mooney; April 5, 1895–July 8, 1953) was an American woman who was convicted of murder in 1934 for killing her husband.

Even before he knew all the facts, Los Angeles County District Attorney Buron Fitts sought the death penalty for Madison.

When pleading her case to Fricke, he refused to reduce the sentence and dismissed the allegations of domestic violence as "ridiculous."

But soon Madison began receiving public support, including from prominent journalist Agness "Aggie" Underwood.

[citation needed] In the fall of 1943, she settled in San Bernardino, where she married her sixth husband, house painter John Wagner.
