Astley Bridge is predominantly a residential district of Bolton in Greater Manchester, England.

It now refers to the large district in the modern Metropolitan Borough of Bolton, but prior to then it simply meant the bridge over Astley Brook which ran through the lower end of the township of Sharples.

[4] After the Public Health Act 1875 was passed by Parliament in that year, Astley Bridge Local Board of Health assumed extra duties as an urban sanitary district, although the Local Board's title did not change.

[7] Since 1974, Astley Bridge has been part of the Metropolitan Borough of Bolton and gives its name to one of Bolton Council's electoral wards, the Astley Bridge ward which includes the Sharples, Bank Top, Eagley Bank, and Horrocks Fold areas.
