Dona nobis pacem (English: Grant us peace) is a cantata written by Ralph Vaughan Williams in 1936 and first performed on 2 October of that year. The work was commissioned to mark the centenary of the Huddersfield Choral Society. Vaughan Williams produced his plea for peace by referring to recent wars during the growing fears of a new one. His texts were taken from the Mass, three poems by Walt Whitman, a political speech, and sections of the Bible. A.V. Butcher has analysed Vaughan Williams' use of the Whitman poems in this composition.
