Cambridge Arts Theatre is a 666-seat theatre on Peas Hill and St Edward's Passage in central Cambridge, England. The theatre presents a varied mix of drama, dance, opera and pantomime. It attracts touring productions, as well as many shows direct from, or prior to, seasons in the West End. Its annual Christmas pantomime is an established tradition in the city. From 1969 to 1985, the theatre was also home to the Cambridge Theatre Company, a national touring company. The Cambridge Arts Theatre was founded in 1936 by the Cambridge economist and statesman John Maynard Keynes.

St Edward's Passage, known in the 18th century as Chain Lane, is a Y-shaped alleyway in Cambridge, England, between King's Parade—opposite the main gate of King's College—and Peas Hill. It houses the entrance and churchyard of the Church of St Edward King and Martyr; the Cambridge Arts Theatre; several cottages; G. David, an independent bookshop run from the same building since 1896; a few businesses; and student accommodation. It is a narrow, dark lane, with riven-stone paving, which opens out onto the much wider and sunnier King's Parade.
