Haydock is a village within the Metropolitan Borough of St Helens, in Merseyside, England. It contains all of the Haydock electoral ward and a section of the Blackbrook electoral ward. The village is located roughly mid-way between Liverpool and Manchester, close to the junction of the M6 motorway and the A580 (East Lancashire Road). It lies within the historic county boundaries of Lancashire. At the 2001 Census, the village had a population of 11,962.

The placename is from Celtic heidd, meaning "barley, wheat" with the suffix -aco meaning "place". An undated source refers to the name as Heidiog. The village is often referred to by the colloquial name of 'Yick', and its inhabitants may be referred to as 'Yickers'.

Haydock was one of the United Kingdom's richest areas in coal and coal mining, having up to 13 collieries working at one time. The last colliery in Haydock – Wood Pit – closed in 1971, bringing to an end coal mining in the area. This site had been the scene of a Mining accident explosion on 7 June 1878 which a subsequent Report of the Inspector of Mines concluded claimed the lives of 189 men and boys. Among them, forty five year old Nathan Boon and his five sons. According to GenUKI 15 victims were not included in the Inspector's report but their names "appeared in the Coroner's Inquest and in some cases in the burial registers". If included, the final death toll would have been 204.

Ron Haydock (17 April 1940, Chicago, Illinois – 14 August 1977, Victorville, California) was an American actor, screenwriter, novelist and rock musician.

His band, Ron Haydock & the Boppers, was sometimes compared to Elvis Presley. Their August, 1959, debut release was "99 Chicks"/"Be-Bop-A Jean." These tunes and 26 other tracks were reissued by Norton Records on the 1996 CD 99 Chicks, which had a vinyl release in 2005.

In the Hollywood B-movie industry, Haydock was an actor and screenwriter, working with director Ray Dennis Steckler, and he also worked as a magazine editor. Haydock used a variety of pseudonyms—Arnold Hayes, Lonnie Lord, Vin Saxon, Don Sheppard and Jerry Lee Vincent. As Vin Saxon, he was the author of adult fiction paperbacks during the 1960s and 1970s. As Arnold Hayes, he wrote graphic stories for Warren Publishing. Haydock was allegedly responsible for discovering actor Edgar Aghassi and setting him on a career in cult horror films.

Haydock's life came to an end in 1977, when he was struck by a truck while hitchhiking after visiting Steckler in Las Vegas. Norton Record's Miriam Linna has written extensively about Haydock for liner notes, magazine articles and the book Sin-A-Rama (2004).

Eric Haydock (born 3 February 1942, Burnley, Lancashire) was the original bass guitarist with The Hollies from December 1962 until 1966. Although considered a great bassist, he was replaced in 1966 by Bernie Calvert, after disputes related to the conduct of the band's managers.
