Ash Holm alum works is a post-medieval industrial site located near Mulgrave Castle in North Yorkshire. The works date from the seventeenth century, when alum production became an important extractive industry in the region.

The site represents the material legacy of Yorkshire's significant contribution to the national alum trade during the early modern period.
