Petty officer Matthew 'Nutty' Curran (1882 – 1938) was an Irish professional heavyweight boxer, from 1900 to 1930.
His fighting name, "Nutty", was derived from the English slang term for someone who is mentally unbalanced.
British heavyweight title bouts featuring Curran were neither recognized by the National Sporting Club (NSC) at the time, nor retroactively by the British Boxing Board of Control, because the bouts did not take place on National Sporting Club premises.
Matthew 'Nutty' Curran's first professional boxing bout was a disqualification defeat by Seaman Jim McDonald at Royal Naval Barracks Gymnasium, Devonport, Devon, in October 1908.
Other notable fight results included: Matthew Curran travelled to Australia for his final professional boxing bout: a retirement defeat by Colin Bell at Capitol Theatre, Sydney, Australia, on 29 August 1921.
