No Offence is a British television police procedural drama on Channel 4, created by Paul Abbott. It follows a team of detectives from Friday Street police station, a division of the Manchester Metropolitan Police (a fictional version of the Greater Manchester Police). The series stars Joanna Scanlan as the protagonist, Detective Inspector Viv Deering. The first series focuses on the team's investigation into the serial murders of young girls with Down syndrome. It was renewed for two further runs. The second series of seven episodes began broadcasting on 4 January 2017, and follows the investigation into Manchester crime boss Nora Attah (Rakie Ayola). It was filmed on location in Manchester.

In the UK, the first episode of No Offence launched with 2.5 million viewers, Channel 4's biggest midweek drama launch for more than three years. Although subsequent episodes lost overnight viewers, dropping as low as 1.2 million, the weekly consolidated series average remained at 2.5 million and finished 47% up on Channel 4's slot average. In France, the first episode of No Offence aired on 29 February 2016 on France 2 and was watched by 5.46 million viewers, 20.4% of the TV audience. The next three episodes were shown back-to-back that evening and together achieved an average 4.6 million viewers, 19.3% of the TV audience.

A third series was confirmed in July 2017. Filming took place in Manchester in March 2018 and it began broadcasting on 13 September 2018. The six-episode series has a political focus, with the main storyline following the attempted murder of a local politician by a far right group. On 19 October 2018, Paul Abbott stated in an interview that he had begun working on ideas for a potential fourth series, but on 28 November 2019, Executive Producer Martin Carr confirmed on Twitter that the show would not be returning.
