Harold Jones (11 January 1906 – 2 January 1971) was a child murderer who committed the murder of two preadolescent girls in Monmouthshire, Wales in 1921 when he was 15. 

Jones was acquitted of the murder of his first victim, 8-year-old Freda Burnell, at Monmouthshire Assizes on 21 June 1921. Just 17 days later, he murdered an 11-year-old neighbour named Florence Little. Jones pleaded guilty to Little's murder and also confessed to having murdered Freda Burnell at his second trial. 

Owing to his being under 16 at the time he committed the murders, Jones escaped capital punishment for his crimes; instead being sentenced to be detained at His Majesty's pleasure on 1 November 1921.[4] Jones was released from prison in 1941, later marrying and fathering a child. He died of bone cancer in 1971 at the age of 64.
