The Amalgamated Society of Paper Makers (ASPM) was a trade union in the United Kingdom.
Many of its founding members split away from the Original Society of Papermakers, which focused on representing workers who did not use machinery.
The new union represented beatermen, machinemen, and finishers, who were seen as the more skilled machine workers in the industry.
A group within the union opposed this, and in 1869 they split away, forming the Modern Society of Paper Makers.
By World War I, it had begun working closely with the National Union of Printing and Paper Workers, and on 1 January 1937 it merged into its successor, the National Union of Printing, Bookbinding and Paper Workers.
