Palazzo Capponi alle Rovinate, Renaissance palazzo in Oltrarno district, Florence, Italy.

Palazzo Capponi alle Rovinate is a Renaissance palazzo in the Oltrarno district of Florence, with a 15th-century facade that mixes Gothic elements, rusticated stonework on the lower floor, and mullioned windows in irregular rows. The building stands on Via de' Bardi, with its rear side facing the Arno River and the hill of San Giorgio behind it.

Niccolò da Uzzano commissioned the palazzo, finished around 1426, possibly to a design by Lorenzo di Bicci. He died in 1431 without heirs, and the building passed to Niccolò Capponi in 1406–1484, remaining with the Capponi family for centuries. The rear facade was rebuilt by Giuseppe Poggi between 1870 and 1873.

The family chapel on the main floor holds an altarpiece by Pontormo and painted glass windows, offering a rare look into the private devotional life of a wealthy Florentine household. Chapels like this one were a common way for noble families to display both faith and artistic taste within their own walls.

The palazzo has two entrances: the main one at Via de' Bardi 36 and a second at Lungarno Torrigiani 25, where Giuseppe Poggi's 1870s rear facade faces the Arno. The building is a private residence, so visits are limited to the exterior; the courtyard, the porphyry lion and the Pontormo chapel are not regularly accessible.

The name 'alle Rovinate' comes from the landslides that repeatedly swept the slope of the Poggio dei Magnoli above the palazzo, culminating in the disastrous slip of 1547. Cosimo I de' Medici then banned new construction there, and an inscription facing the palace still records the prohibition.
