Twm o'r Nant ('Tom from the Brook') was the pseudonym of a Welsh language dramatist and poet, Thomas Edwards (January 1739 – 3 April 1810), also known as Tom of the Dingle.

The couple settled in Denbigh, where Edwards worked hauling timber, performing in his interludes throughout North Wales and selling printed copies of them.

After financial problems caused by the bankruptcy of an uncle, for whom he had stood surety, Edwards moved to South Wales, where he again worked in timber haulage and for a time kept an inn in Llandeilo.

His failure to win the main prize at the Corwen Eisteddfod in 1789 may have been due to a dispute over an impromptu composition competition with Walter Davies (Gwallter Mechain), in which Edwards was supported by David Samwell (Captain Cook's surgeon).

Samwell named Edwards The Cambrian Shakespeare and gave him a silver pen as a consolation prize for having been unfairly beaten.

[7] George Borrow devotes two chapters to Edwards in his 1862 travel book Wild Wales: Its People, Language and Scenery.
