Cock-a-Doodle Dandy is a 1949 play by Irish dramatist Seán O'Casey.
It is a parable of mid-century Irish rural life, symbolising the struggle between repression and liberty.
Initially it was regarded as anti-Catholic and was banned from professional public performance in the UK by the Lord Chamberlain.
The World premiere of the play took place at the People's Theatre, Newcastle upon Tyne in 1949.
Under the headline "A Play to Arouse both Anger and Pity", it was described as "a performance of infinitely better quality than I had expected to lie in the capacity of mere Anglo-Saxons, unlearned in the tricky inflexions of O'Casey's Nyadnanave."
