Alston Hall is a 19th-century Victorian gothic style country mansion located in Longridge (near Preston) in Lancashire, England.

Alston Hall, designed by the architect Alfred Darbyshire, was built c.1876 for John Mercer, a Newton-le-Willows colliery owner.

It passed down to his grand-daughter, who was a nun, and was then sold to the Eccles cotton manufacturing family who sold it in turn to William Birtwistle, another wealthy cotton industrialist.

In 1974 it was purchased by Lancashire County Council and converted to a residential training centre.
