Stefanos Lazaridis (28 July 1942 – 8 May 2010) was a British stage designer, best known for his work in opera. Originally intended for a business career, he studied stage design in London, and was quickly in demand in theatres and opera houses, working with John Copley and other directors.
Originally his style was lavish and naturalistic, but he changed to a less traditional style, working with David Pountney and other more avant garde directors at English National Opera and elsewhere.
He occasionally directed operas, and was for a short time director of the Greek National Opera.
