Lesley Molseed (14 August 1964 – 5 October 1975), born Lesley Susan Anderson, was an English schoolgirl who was abducted and murdered on 5 October 1975 in West Yorkshire. Stefan Kiszko, an intellectually disabled man who lived near Molseed's residence in Greater Manchester, was wrongly convicted in her murder and served sixteen years in prison before his conviction was overturned. His mental and physical health had deteriorated in prison, and he died twenty-two months after his release in February 1992 – before he could collect the money owed to him for his wrongful conviction. Kiszko's ordeal was described by one British MP as "the worst miscarriage of justice of all time."
