The Basilica Palladiana is a Renaissance building in the central Piazza dei Signori in Vicenza, north-eastern Italy. The most notable feature of the edifice is the loggia, which shows one of the first examples of what have come to be known as the Palladian window, designed by a young Andrea Palladio, whose work in architecture was to have a significant effect on the field during the Renaissance and later periods.

Inside the building is the Museo Palladiano, with models, designs, and other work by the architect. There is a café on the upper terrace. Behind the Basilica is Piazza delle Erbe, which is filled by Vicenza’s farmers’ market on Thursday mornings.
