Mark Orange is a visual artist from Belfast, Northern Ireland, living and working in New York since 1999. His work in audio, video, photography and installation has been shown at galleries internationally, including Artists Space, Swiss Institute, Participant Inc, and Anthology Film Archives in New York, as well as Overgaden Copenhagen, Temple Bar Gallery Dublin, Cornell University Ithaca, and Model Arts and Niland Gallery Sligo. In 2017, Orange presented McCullough Mulvin Orange, a major solo exhibition project that took place across five venues in Dublin, including the Irish Architecture Foundation, Temple Bar Gallery & Studios, and Trinity College.

The artist was a founding member of Belfast artist-run organization Catalyst Arts in 1993, where he was closely involved in curating a series of exhibitions and projects in non-gallery spaces. This experience directly fed into his own art practice, which often draws on post-minimalist and site-specific traditions. He has produced a series of works based on collaborations with contemporary architects; and architectural space and the figure of the architect—as well as a strand of counter-architectural practice stretching back to Georges Bataille and the Surrealists—has remained a focus of his work.

Orange has received studio residency awards at Yaddo and the Irish Museum of Modern Art, and was a resident artist on the PS1 International Studio Program, and at the Arts and Humanities Research Institute at Trinity College Dublin. He has received project awards from the Arts Council of Ireland, the Arts Council of Northern Ireland, and Dublin City Council, and twice been a recipient of the EVA International Biennial prize. Three of his film works are held in the collection of LUX, London.

Mark Orange's work has been featured in magazines and journals including Artforum, Art Monthly, Contemporary, Time Out New York, CIRCA, The Guardian, The Irish Times, and The Sunday Times, and in 2011, he was selected as one of the representative artists of the new millennium for the publication 'Creative Ireland: The Visual Arts'.
