Bacchus, Venus and Ariadne is an oil painting executed in Venice in 1576–77 by the Italian painter Jacopo Tintoretto which hangs in the Sala dell'Anticollegio at the Doge's Palace (the Pallazzo Ducale) in Venice.

It is one of four almost square paintings on mythological subjects in the same room which were commissioned to celebrate the government of Doge Girolamo Priuli (1486–1567).

[1] It depicts the god Bacchus (Greek: Dionysis) arriving from the sea with a wreath and a skirt of vine leaves, bearing a bunch of grapes and a marriage ring.

Theseus subsequently abandoned her on the island of Naxos where she was discovered by Bacchus.

Ariadne personified Venice, favoured by the gods and crowned in glory, the marriage representing the union of Venice with the sea.
