John Payne Collier (London, 11 January 1789 – 17 September 1883), was an English Shakespearian critic and forger.
He was librarian to the Duke of Devonshire, secretary to the Royal Commission on the British Museum , and had access to the chief collections of early English literature throughout the kingdom.
Collier used these opportunities to effect a series of literary fabrications. Over the next several years he claimed to find a number of new documents relating to Shakespeare's life and business. After New Facts, New Particulars and Further Particulars respecting Shakespeare had appeared and passed muster.
