Dione is a 1720 tragedy by the British writer John Gay. It marked a departure from the comedies he had made his name with. It was also the first full-length play he had written alone since The Wife of Bath in 1713. It is likely Gay started writing it either before or during a recent trip he had made to Paris. Gay wrote another tragedy The Captives, which was staged at Drury Lane, before turning back to comedy to produce his greatest success The Beggar's Opera.
