Fearless is a six-part British crime thriller television drama series created by screenwriter Patrick Harbinson and broadcast on ITV in 2017. The series follows human-rights lawyer Emma Banville (Helen McCrory) as she tries to prove convicted murderer Kevin Russell innocent of the murder of schoolgirl Linda Simms 14 years earlier. Russell asserts that he is innocent of the crime, and Emma believes that his conviction was a miscarriage of justice. She goes to extreme lengths to discover the truth.

Supporting cast includes Michael Gambon as influential former Deputy Secretary to the Cabinet Office Sir Alastair McKinnon, Jonathan Forbes as Emma's colleague Dominic Truelove, Wunmi Mosaku as DCS Olivia Greenwood, the Investigating Officer on the Linda Simms case, and John Bishop as Emma's boyfriend Steve Livesey.

Filming for the series began in September 2016 in London and East Anglia. The series debuted on ITV in the UK on 12 June 2017 and has received positive reviews, with critics praising Helen McCrory's performance. However, the show was cancelled in March 2018 after one series.
