List of awards and nominations received by Line of Duty

Line of Duty is a British police procedural and serial drama consisting of six series that was created by Jed Mercurio and broadcast by the British Broadcasting Corporation (BBC). The first three series spanned a total of 17 episodes and aired on BBC Two between 2012 and 2016. The remaining three series comprised 19 episodes and aired on BBC One from 2017 to 2021. Produced by World Productions, the series was primarily filmed in Belfast although filming for the first series took place in Birmingham. Mercurio wrote all 36 episodes and serves as an executive producer alongside Simon Heath and Stephen Wright. It was distributed internationally Content Media Group which was eventually purchased by Kew Media Distribution and later ITV Studios following Kew Media's collapse.

The series primarily follows the actions of Anti-Corruption Unit 12 (AC-12), a task force located within the fictional Central Police Constabulary. AC-12 is led by Superintendent Ted Hastings, portrayed by Adrian Dunbar, who appeared in the first series and was promoted to the main cast beginning with the second series. Martin Compston and Vicky McClure also starred in all six series as AC-12 officers Steve Arnott and Kate Fleming. Each series features an additional actor as part of the main cast who portrays a police officer that is being investigated by AC-12. These roles were performed by Lennie James in series one, Keely Hawes in series two, Daniel Mays in the third series, Thandie Newton in series four, Stephen Graham in series five, and Kelly Macdonald in the sixth and final series. Craig Parkinson was an additional member of the second and third series cast, while Hawes' role extended into the third. Parkinson also appeared in the first series prior to being promoted. The characters of Parkinson and Hawes were both killed off at the end of series three; Parkinson however, appeared as a guest star in one episode of each of the two following series in flashback scenes. Jessica Raine starred in a single episode of the second series and Jason Watkins appeared in two episodes of the fourth series; both were credited with the other principal cast members. Additionally, Anna Maxwell Martin was also featured as part of the starring cast in the fifth and sixth series, but only appeared in the latter portion of each series.
