The second series of the British police procedural television programme Line of Duty, was broadcast on BBC Two between 12 February and 19 March 2014.

The series follows the actions of the fictional Anti-Corruption Unit 12. AC-12 is led by Superintendent Ted Hastings (Adrian Dunbar) who is assisted by his team DS Steve Arnott (Martin Compston), DC Kate Fleming (Vicky McClure), and DI Matthew "Dot" Cottan (Craig Parkinson). The unit investigates DI Lindsay Denton (Keely Hawes), the sole survivor of an attack on police officers, and the possibility of a corrupt police officer conspiring to murder a protected witness in the ambush. Jessica Raine stars in a single episode as DC Georgia Trotman. Beginning with this series, Dunbar and Parkinson are credited as main cast members in the opening credits. Supporting characters include DCC Mike Dryden (Mark Bonnar), Jo Dwyer (Liz White), DCS Lester Hargreaves (Tony Pitts), DC Nigel Morton (Neil Morrissey), and Tommy Hunter (Brian McCardie).

The series was created and written by Jed Mercurio, who also serves as an executive producer. Filming took place in Belfast in 2013. Six episodes were directed by Douglas Mackinnon and Daniel Nettheim with cinematographer Ruairi O'Brien. The series received positive reviews and multiple accolades, most notably for Hawes performance as Denton, leading to the commission of a third and fourth series.
