Peter Grimes, Op. 33, is an opera in three acts by Benjamin Britten, with a libretto by Montagu Slater based on the section 'Peter Grimes', in George Crabbe's long narrative poem The Borough. The 'borough' of the opera is a fictional small town that bears some resemblance to Crabbe's – and later Britten's – home of Aldeburgh, Suffolk, on England's east coast.
