Ronald Joseph Dominique (born 1964) is an American serial killer from the Bayou Blue area of Houma, which is in Terrebonne Parish in southeastern Louisiana.

Following his arrest on December 1, 2006, Dominique confessed to the rape and murder of at least 23 men over a ten-year period beginning in 1997, in Terrebonne Parish, Lafourche Parish, Iberville Parish and Jefferson Parish in suburban New Orleans. He has been charged with multiple cases of rape and first-degree murder. Dominique is suspected of killing 23 men.

In his confession, Dominique, who is reportedly gay, said he frequented area gay bars and targeted men he thought would be willing to have sex for money.

He was investigated following a police report by a man who refused to let Dominique tie him up. The most recent victim, Christoper Sutterfield, had died about two months earlier.

On September 23, 2008, Dominique was sentenced to eight life sentences after confessing to raping and killing his male victims over a ten-year period. Dominique had pleaded guilty to first-degree murder in a deal to avoid the death penalty. He is incarcerated at the Louisiana State Penitentiary in Angola.
