Miles O'Donovan is a character from the Grand Theft Auto series who appears in Grand Theft Auto: Liberty City Stories as a minor role. He is the Mayor of Liberty City from 1998 until 2001. In Grand Theft Auto III, O'Donovan was voiced by the late John Braden.
Miles O'Donovan ran against Mayor Roger C. Hole in the previous election for the position of Mayor in Liberty City in 1992. However, O'Donovan failed but had gained support due to a series of scandals that Mayor Hole was involved in. It is rumored that O'Donovan himself has a past of corruption, drug abuse, and prostitution.
He runs for Mayor a second time in a special election following Mayor Hole's death at the hands of Toni Cipriani. Cipriani and Salvatore Leone (Don of the Leone Family) oppose O'Donovan with their own candidate: Donald Love. Cipriani campaigns for Love, however after a link between Love and the Leone Family are found, Love loses most of his popularity and fortune.
Following his election victory, O'Donovan helped to end the industrial action of ferry workers on Portland and Staunton Island. O'Donovan promised that the ferries would remain in Liberty City and that jobs would not be lost. Despite his promise, the ferries stopped transporting between Portland and Staunton Island between 1998 and 2000 (in Grand Theft Auto Advance the ferry terminals, by 2000, had been demolished and paved over}.
O'Donovan, as one of his first moves, has the Liberty City Police Department arrest Salvatore Leone, putting him on trial. Salvatore Leone is released after Cipriani kills Paulie Sindacco and increases activities against the Sindacco Family and the Forelli Family. Salvatore, in his belief that O'Donovan will drop the charges, leads to Massimo Torini (member of the Sicilian Mafia and opponent of Salvatore) to kidnap O'Donovan. He takes the captive Mayor to Portland Rock, and ends up indebted to Toni and Salvatore after they rescue him. Salvatore tells the Mayor that he belongs to him, and from then on has the Mayor in his pocket.
O'Donovan does not appear in Grand Theft Auto III, but is mentioned on the Liberty Tree website. O'Donovan is said to have endorsed nail guns  (his brother is CEO of Donovan Hardware) and has done little good for Liberty City, except the increase of hardware stores by two folds since his election. This includes little work on transportation, such as the closure of the ferries and lack of improvement on the Portland El. However, O'Donovan had made some improvements, including promising to renew the Red Light District's license and revamp the area.  O'Donovan, in April 2001, also purchases police helicopters for the Liberty City Police Department
