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, an exhibition 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 events at offsite locations. This experience directly fed into his own art practice, which frequently draws on post-minimalist and site-specific traditions. Architectural space and the figure of the architect have remained a consistent focus of many of these works, which often foreground minor narratives to navigate alternative paths through built space. Key projects have included a trilogy of 16mm short films shot at landmark locations in New York; a group of works that explore 'open 24 hours' as an abstracting ideological account of the modern city; and a suite of collaborative audio and video installations that have sought to return contemporary architects to the spaces they have designed—in playful or unexpected ways that serve to displace top-down models of creativity.

Orange has been an artist in residence at the Arts and Humanities Research Institute at Trinity College Dublin; PS1, New York; Yaddo, Saratoga Springs; and the Irish Museum of Modern Art, Dublin. He has received awards from the Arts Councils of Ireland and Northern Ireland, 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 written about in publications including Artforum, Art Monthly, Contemporary, Time Out New York, CIRCA, The Guardian, The Irish Times, and The Sunday Times; in 2011, he was selected as one of the representative artists of the new millennium for the publication 'Creative Ireland: The Visual Arts'.
