Broadchurch is a British crime drama television series broadcast on ITV for three series between 2013 and 2017. It was created by Chris Chibnall, who acted as an executive producer and wrote all 24 episodes; it was produced by Kudos in association with Imaginary Friends Productions Ltd. The series is set in Broadchurch, a fictional English town on the coast of Dorset; it focuses on Detective Inspector Alec Hardy (David Tennant) and Detective Sergeant Ellie Miller (Olivia Colman). Other members of the ensemble cast appearing in all three seasons are Jodie Whittaker, Andrew Buchan, Arthur Darvill, Carolyn Pickles, Jonathan Bailey, Matthew Gravelle, Charlotte Beaumont and Adam Wilson.

The first series, which premiered on 4 March 2013, focuses on the death of local 11-year-old Danny Latimer and the impact of grief, mutual suspicion and media attention on the town. Danny's family, his mother, Beth (Whittaker), father, Mark (Buchan) and sister, Chloe (Beaumont), is a key focus. The second series, which premiered on 5 January 2015, follows the dual story lines of bringing Danny's killer to justice and a case from the past returning to haunt Hardy. The third and final series, which premiered on 27 February 2017, focuses on the rape of a local woman, Trish Winterman (Julie Hesmondhalgh), at a birthday party, while the Latimer family goes to extreme lengths to move on from Danny's death. Chibnall has stated that the third series was the last and that he had originally envisioned Broadchurch as a trilogy.

All three series received positive reviews and praise for the writing, cinematography, performances (particularly Tennant and Colman) and character development.
