Desmond "Dessie" Noonan (8 August 1959 – 19 March 2005) was an English organised crime figure from Manchester, who acted as a political fixer for the Noonan crime family.
He and his younger brother, Dominic Noonan, were suspected by police to be responsible for at least 25 unsolved murders during their 20-year reign over Manchester's underworld.
Mainly because of the very dangerous contacts Desmond Noonan had made during his reign as "Britain's number one
Gangster", his family was at the end of the 1990s known as "one of the most notorious crime families in British history".
