Caffè Quadri (Italian pronunciation: [kafˌfɛ kˈkwaːdri]) is a coffeehouse located in the Procuratie Vecchie of Piazza San Marco, Venice.^[1] It was established in 1775.

The restaurant underwent a first important renovation in 1830, under the management of the Vaerini brothers, who expanded both the spaces and the activities, purchasing the upper floor that was used as a restaurant.^[2] The ground floor was decorated with pastel stuccos, with a prevalence of green and yellow colors, and completed with views and scenes of Venetian life, the work of the painter Giuseppe Ponga, inspired by the style of Pietro Longhi.^[3]

The property together with some other shops here are owned by Russian conductor Valery Gergiev as a part of the vast real estate inheritance of the philanthropist Yoko Nagae Ceschina who has died in 2015.^[4]
