The Bagatti Valsecchi Museum is a historic house museum in the Montenapoleone district of downtown Milan, northern Italy.

The Bagatti Valsecchi Museum's permanent collections principally contain Italian Renaissance decorative arts (such as maiolica, furniture, tapestry, metalwork, leather, glassware and precious table-top coffers made of ivory, or “stucco and pastiglia”), some sculptures (including a Madonna and Child lunette by a follower of Donatello), and many paintings.

European Renaissance weapons, armor, clocks and a few textiles and scientific and musical instruments complete the collection assembled by the Barons Bagatti Valsecchi, and displayed in their home, as per their wishes.

The Bagatti Valsecchi Museum, although originally intended as a private home, not a gallery, has an interesting collection of Italian Renaissance paintings.
