Fiuggi is a cold (12.4°C), oligomineral spring water drawn from the Fonte Bonifacio VIII in the town of Fiuggi, southeast of Rome. It has been used since at least the 14th century as a drinking cure for kidney stones, a reputation dating back to Pope Boniface VIII and later praised by Michelangelo. The water is notable for its low mineral content and presence of humic and fulvic acids, and in 2022 Acqua Fiuggi was recognized as a Historical Trademark of National Interest.

Pope Boniface VIII reportedly credited the spring water with curing his kidney stones in the late 13th century, and Michelangelo praised its effects in a 1549 letter, calling kidney stones 'the only kind of stone I couldn't love.' The water was subsequently sent in bottles to European royalty.
