The Pembrokeshire Murders is a Welsh three-part television drama miniseries based on the Pembrokeshire murders by Welsh serial killer John Cooper. In 2006, newly promoted Detective Superintendent Steve Wilkins decided to reopen two unsolved 1980s murder cases linked with a string of burglaries. New advances in technology for forensic DNA analysis, witness reports and artists impressions of the suspect led to Dyfed-Powys Police reviewing a 1989 episode of Bullseye, which led to the serial killer finally being caught. It premiered on ITV on 11 January 2021.

The drama is the thirteenth in a series of ITV mini-series featuring notorious British murder cases of the past two centuries, following on from This Is Personal: The Hunt for the Yorkshire Ripper (2000), Shipman (2002), A Is for Acid (2002), The Brides in the Bath (2003), See No Evil: The Moors Murders (2006), Appropriate Adult (2011), Dark Angel, In Plain Sight (both 2016), Little Boy Blue (2017), Manhunt (2019), White House Farm, and Des (both 2020).
