JonBenét Patricia Ramsey (August 6, 1990 – December 25, 1996) was an American child beauty pageant queen made famous by her murder and the subsequent media coverage. She was found dead in the basement of her parents' home in Boulder, Colorado, nearly eight hours after she was reported missing. The case is notable in both its longevity and the media interest it has generated in the United States. After several grand jury hearings, the case is still unsolved. In February 2009, the Boulder Police Department took the case back from the district attorney and re-opened the investigation.

JonBenét Ramsey was born in Atlanta, Georgia, but the family relocated when she was nine months old. Her first name is a portmanteau of her father's first and middle names, John Bennett; her middle name is that of her mother, the late Patricia "Patsy" Ramsey, who enrolled her daughter in a variety of different beauty pageants in several states. In addition, she funded some of the contests in which Jon participated in rock climbing, violin lessons and other activities.

JonBenét is buried in Saint James Episcopal Cemetery in Marietta, Georgia, next to her mother.
