Joanna Marie Parrish (30 July 1969 – 16 or 17 May 1990) was a British tutor and language student from Newnham on Severn, Gloucestershire, England, who was murdered in the Burgundy region of France while working at a local school as part of her degree course in 1990.

Parrish, a University of Leeds undergraduate who was studying French, disappeared on the night of 16–17 May after placing an advertisement in a local Burgundy newspaper offering private English lessons, and arranging to meet a man who it is believed contacted her with details of a potential student.

Her parents had planned to visit her in France to take home her belongings, while Parrish herself would travel on to Czechoslovakia to join her boyfriend, a fellow Leeds student who had also been working overseas.

[5] The theory that Fourniret was responsible gained added strength when his wife claimed to have witnessed her husband kill a young woman in Auxerre before dumping her body into the river.

[10] Parrish's family expressed their frustration at the decision by French authorities, particularly as in France, charges cannot be brought against a suspect if a murder case remains inactive for ten years.

[4] In June 2012, judges at the Paris appeals court decided to reopen the investigation after the emergence of fresh evidence identifying a new suspect described as "a man with a serious criminal record".

A former girlfriend of the individual, known as "TV", told police of an evening on which she recalled seeing the suspect return home "with scratch marks on his face" and "a jean bag looking similar to Miss Parrish's."

[15] On 19 December 2023, Olivier was convicted of playing a part in the rape and murder of Parrish and Doemece, and helping to kidnap Mouzin, and was sentenced to life imprisonment.
