Chandra Ann Levy (April 14, 1977 – c. May 1, 2001) was an American intern at the Federal Bureau of Prisons in Washington, D.C., who disappeared in May 2001. She was presumed murdered after her skeletal remains were found in Rock Creek Park in May 2002. The case attracted attention from the American news media for several years.

Due to a miscommunication, the Metropolitan Police Department of the District of Columbia (MPD) failed to follow its own search parameters in Rock Creek Park, leaving Levy's body to decompose for a year. Further, the MPD had been informed, but soon dismissed the information that Ingmar Guandique, already arrested for attacking women in Rock Creek Park, had confessed to attacking Levy. The MPD instead put much of its focus on the revelation that Levy had been having an extramarital affair with Congressman Gary Condit, a Democrat then serving his fifth term representing California's 18th congressional district and a senior member of the House Permanent Select Committee on Intelligence. Condit was never named as a suspect by police; he was eventually cleared of any involvement. Due to the cloud of suspicion raised by the intense media focus on the missing intern and the later revelation of the affair, Condit lost his bid for re-election in 2002.

Following a series of investigative reports by The Washington Post in 2008, the MPD followed up and finally obtained a warrant, on March 3, 2009, to arrest Ingmar Guandique, identified and dismissed by the MPD eight years earlier. He had been convicted of assaulting two other women in Rock Creek Park around the time of Levy's disappearance and was still in prison on those convictions when the arrest warrant on Levy's death was issued. Prosecutors alleged that Guandique had attacked and tied up Levy in a remote area of the park and left her to die of dehydration or exposure. In November 2010, Guandique was convicted of murdering Levy; he was sentenced in February 2011 to 60 years in prison. In June 2015, Guandique was granted a new trial. On July 28, 2016, prosecutors announced that they would not proceed with the case against Guandique and would instead seek to have him deported. In March 2017, Guandique lost his bid to remain in the United States and was deported to his native El Salvador on May 5, 2017. Levy's murder remains unsolved.
