Arms and the Man is a comedy by George Bernard Shaw, whose title comes from the opening words of Virgil's Aeneid, in Latin: Arma virumque cano ("Of arms and the man I sing").

The play was first produced on 21 April 1894 at the Avenue Theatre and published in 1898 as part of Shaw's Plays Pleasant volume, which also included Candida, You Never Can Tell, and The Man of Destiny. Arms and the Man was one of Shaw's first commercial successes. He was called on to stage after the curtain, where he received enthusiastic applause. Amidst the cheers, one audience member booed. Shaw riposted, "My dear fellow, I quite agree with you, but what are we two against so many?"

Arms and the Man humorously exposes the futility of war and the hypocrisies of human nature.
