Ronald "Ronnie" Kray (24 October 1933 – 17 March 1995) and Reginald "Reggie" Kray (24 October 1933 – 1 October 2000), twin brothers, were English criminals, the foremost perpetrators of organised crime in the East End of London during the 1950s and 1960s. With their gang, known as "The Firm", the Krays were involved in murder, armed robbery, arson, protection rackets and assaults.

Ronald "Ron" and Reginald "Reggie" Kray were born on 24 October 1933 in Haggerston, East London, to Charles David Kray (10 March 1907 – 8 March 1983), a wardrobe dealer, and Violet Annie Lee (5 August 1909 – 4 August 1982). The brothers were twins, with Reggie born ten minutes before Ronnie. Their parents already had a six-year-old son, Charles James (9 July 1927 – 4 April 2000). A sister, Violet (born 1929), died in infancy.
