Domenico Fetti (* 1589 in Rome; 1624 in Venice; also Domenico Feti) was an Italian baroque painter.
Fetti studied with Lodovico Cigoli and then went to Mantua at the instigation of Duke Ferdinand Gonzaga, where his main works were created, therefore called Mantuano. He died in Venice in 1624. Fetti was a naturalist, who in his coarseness followed the opinion of Caravaggio; in Mantua he sought to imitate Giulio Romano, which he only achieved in an external way, while in Venice he emulated the Venetians.
His treatment has something pasty and bacony; his colouring is sometimes strong, but very often unpleasant due to black shadows. In Mantua (especially in the cathedral) his main works are to be found, partly in oil, partly in fresco; the galleries of St. Petersburg, Vienna, Paris, Munich and Dresden preserve other works.
