Republic of Doyle is a Canadian comedy-drama television series set in St. John's, Newfoundland and Labrador, which aired on CBC Television from January 6, 2010, to December 10, 2014.

The show stars Allan Hawco as private investigator and former police officer Jake Doyle and Seán McGinley as his father, retired police officer Malachy Doyle. They partner as private investigators with Rose Doyle, Malachy's second wife, played by Lynda Boyd, in St. John's. Krystin Pellerin stars as Constable/Sergeant Leslie Bennett, with Mark O'Brien as Desmond "Des" Courtney, who works with the Doyles, and Marthe Bernard as Katrina "Tinny" Doyle, Jake's niece and Malachy's granddaughter. Their cases involve them in all sorts of dealings – not all of them on the right side of the law.
