Peter Grimes is an opera by Benjamin Britten, with a libretto adapted by Montagu Slater from the Peter Grimes section of George Crabbe's poem The Borough.
It was first performed at Sadler's Wells in London on June 7, 1945, conducted by Reginald Goodall. It was the first of Britten's operas to be a critical and popular success. It is still widely performed, both in the UK and internationally and is considered part of the standard repertoire. In addition, the "Four Sea Interludes" were published separately and are frequently performed as an orchestral suite.
