Mabel Ma Collings Bell, known as Mabel Ma Bell, was an 83-year-old white woman who was assaulted in her Arcadia, California home on the evening of May 29, 1985. She and her sister Florence Lang were both attacked during the intrusion. Mabel Bell suffered severe injuries and died of those wounds on July 15, 1985, at Southern California Methodist Hospital.

The attacker is identified as Richard Ramirez, the so-called Night Stalker, whose series of home invasions, assaults and murders in California occurred in 1984–1985. Ramirez was arrested on August 31, 1985, and was later convicted of multiple counts of murder, including the death of Mabel Bell, along with numerous counts of attempted murder, sexual assault and burglary.
