Maria Ladenburger was a 19-year-old medical student from Freiburg im Breisgau, Baden-Württemberg, Germany, who was found raped and drowned on 16 October 2016 in the river Dreisam. On 3 December 2016, Freiburg police arrested Hussein Khavari, who had been identified by a hair found at the crime scene, and a CCTV recording from inside a tram. DNA evidence linked him to the crime scene and he was ultimately convicted.

Rape in Germany is defined by Section 177 of the Criminal Code of Germany. The definition of rape has changed over time from its original formulation in the penal code established in 1871, as extramarital intercourse with a woman by force or the threat of violence. In 1997 laws were amended to criminalize marital rape, incorporate gender-neutral language, and recognize the effect of psychological coercion. In 2016 German laws were rewritten to remove a previous requirement that a victim physically resist their assailants and be overcome by force. The new law recognized any physical or verbal cue that one party does not consent to sexual contact. It also mandated deportation for migrants convicted of sexual assault, made it easier to prosecute rapes committed by groups, and criminalized other types of unwanted sexual contact, such as groping or fondling. The changes followed a series of high-profile cases that sparked public outrage at the inadequacy of the law.
