The broadcaster and author, who is a graphic design and illustration graduate from GSA, served as assistant head of design at the National Museum of Antiquities in Edinburgh.
She went on to present Channel 4's ground breaking music programme The Tube and set up a successful TV production company Gallus Besum. Ms Gray has also been a regular contributor to a number of publications including the Sunday Herald and won Columnist of the Year in the 2001 Scottish Press Awards.
She has also written a number of books ranging from horror to the definitive history of Kelvingrove Art Gallery and Museum.
Professor Tom Inns, director of Glasgow School of Art, said: "It is a great pleasure to welcome Muriel Gray as chair of the board of governors.
"She has made a hugely important contribution to the cultural life of Scotland as a writer, broadcaster and businesswoman and is already a great inspiration to our students.
"Since graduating from GSA, Muriel has always been generous with her time supporting the institution in many ways.
"Most recently she served as vice chair of the international jury which selected Steven Holl as the architect to design GSA's new building and she is a member of the development trust for phase two of GSA's Garnethill campus development.
"I am looking forward to working closely with Muriel as we take Glasgow School of Art forward, further developing its reputation at such an exciting and crucial moment in the school's history."
Ms Gray said: "I am thrilled and honoured to be inheriting the post of chair of the board of governors, particularly at such an exciting and crucial moment in the school's history."
