Josh Wirz is an artist based in Glasgow. He creates installations and live events that centre on the creative use of live-streaming technology. His work explores the technology's creative potential alongside its capacity to broaden access to live art, continuing a formal inquiry into streaming that was central to the performance industry's response to the Covid-19 pandemic. His work has been described as 'vulnerable yet heroic', 'a morbid curiosity', and 'an intense, slightly worrying, and very beautiful experience'. Wirz's intention is to create work that is absurd, fragile and direct.

He is a co-founder and co-director of Horsepower, an artist-run initiative in the East End of Glasgow supporting emerging and early-career artists through solo exhibitions. In 2026 he launched Spinach Live, a virtual platform for live performance. He is part of a long-term collaboration with Swedish artist Axel Berger (2017–present), together disrupting the Shell PLC 2024 International Shareholders Meeting and is engaged in the ongoing research project Frenemy with University of Cambridge sociologist Isabelle Higgins (2023–present). He is also the founder and co-director of the Glasgow Clowning Jam, a free meet-up group for clowns in Glasgow.

His work has been shown in the UK and abroad, most recently at FormaHQ, PINK Manchester, IAC Malmö, The University of Cambridge, Refractive Collective, Lewisham Art House and Gossamer Fog.
