The ABTT Theatre Show is an annual trade show hosted in London and organised by registered charity, the Association of British Theatre Technicians. The ABTT Theatre show draws exhibitors and visitors from all over the world interested in topics such as lighting, audio visual, scenography, rigging, set construction, technical theatre and related technologies.

It has been developed by the ABTT to be relevant across theatre, TV, Film and commercial work. So a broad range of technical disciplines are covered, being relevant to venue operators, production staff, theatre consultants and students addressing issues of Health and Safety, Codes of Practice, Live Performance, Academic Development and other relevant matters.

The ABTT Theatre Show was last presented on the 5th and 6th June 2019, where the new exhibition layout and comprehensive programme of events saw a 13% increase in attendance on 2018.
