The Art Workers' Guild is an organisation established in 1884 by a group of British painters, sculptors, architects, and designers associated with the ideas of William Morris and the Arts and Crafts movement. The guild promoted the 'unity of all the arts', denying the distinction between fine and applied art. It opposed the professionalisation of architecture – which was promoted by the Royal Institute of British Architects at this time – in the belief that this would inhibit design. In his 1998 book, Introduction to Victorian Style, University of Brighton's David Crowley stated the guild was "the conscientious core of the Arts and Crafts Movement".

John Belcher was an English architect, and president of the Royal Institute of British Architects.
