Greek is an opera in two acts composed by Mark-Anthony Turnage to a libretto adapted by Turnage and Jonathan Moore from Steven Berkoff's 1980 verse play Greek. The play and the opera are a re-telling of Sophocles's Greek tragedy Oedipus Rex with the setting changed to the East End of London in the 1980s. The opera was first performed on 17 June 1988 in the Carl-Orff-Saal of the Gasteig, Munich, in a co-production by the Munich Biennale, the Edinburgh International Festival and the BBC.
