The Doni Tono or Doni Madonna is a painting by the Italian Renaissance master Michelangelo Buonarroti (c. 1503), the only known preserved panel picture by the Florentine artist. It is preserved in the Uffizi of Florence in its original frame, designed by Michelangelo himself. The painting was most likely commissioned by Angelo Doni, a wealthy weaver, to commemorate his marriage to Maddalena Strozzi of the Strozzis, a powerful Tuscan family, famous for their opposition to the Medici rule. The painting is in the form of a tondo, or round frame, which is frequently associated with marriage in the Renaissance.
