The Traditional Drama Research Group (TDRG) encourages research into all aspects of traditional drama. The TDRG is essentially an informal group of researchers in the British Isles, Europe and North America who have an academic interest in the history and performance of all forms of traditional drama. Whilst a unifying influence tends to be an interest in the British & Irish folk play or mumming-play tradition, individual studies have encompassed topics as diverse as shadow puppets, miracle plays, the social history of the Fool, the folk drama of Russia and of the several native and immigrant American communities.

The TDRG was formed in 1980 and was initially closely linked to the University of Sheffield. When TDRG was most active, a newsletter (Roomer) was published, conferences were organised, and a journal (Traditional Drama Studies) was published.
