San Quentin State Prison spokesman Lt. Sam Robinson says Ramirez, 53, died Friday morning.
Ramirez was convicted of 13 murders that terrorized Southern California in 1984 and '85, and sentenced to death.
Satanic symbols were left at murder scenes and some victims were forced to "swear to Satan" by the killer, who entered homes through unlocked windows and doors.
Ramirez was captured and beaten in 1985 by residents of an East Los Angeles neighborhood while attempting a carjacking.
Born in El Paso, Texas, Ramirez was the youngest of six children and epileptic. His father reportedly described him as "a good boy," until, by the time he was 18, he became involved with drugs.
A 1989 TV movie about the case, Manhunt: Search for the Night Stalker, starred actor Gregory Cruz as Ramirez.
