Merseybeat was a British police procedural television series, with a total of four series broadcast between 2001 and 2004. The programme follows the personal and professional lives of one shift of police officers from the fictional Newton Park police station in Merseyside, England. 

In 2001, prior the launch of the series, Merseybeat attracted controversy due to alleged similarities between its pilot episode and the murder of James Bulger, though the BBC defended the series, saying "there are no associations with the tragic case of James Bulger". 
In late 2003, when Merseybeat commenced its fourth series, it underwent a major revamp, including the scrapping of the title sequence and theme tune, which was replaced with a record from Liverpudlian band Cast. A more "gritty" approach to the drama was also part of the revamp, with the introduction of the station's CID and Mark Womack, formerly of Liverpool 1 as DI Hammond. 

For the first three series, filming took place mainly in the Cheshire towns of Widnes and Runcorn (both within the Borough of Halton), making heavy use of local landmarks such as the Silver Jubilee Bridge and Fiddlers Ferry power station. The police station itself was a disused Golden Wonder factory, which is located in Widnes. For the fourth and final series, filming was moved to Liverpool.
