Villa Barbaro, also known as the Villa di Maser, is a large villa at Maser in the Veneto region of northern Italy. It was designed and built by the Italian Renaissance architect Andrea Palladio, with frescos by Paolo Veronese and sculptures by Alessandro Vittoria, for Daniele Barbaro, Patriarch of Aquileia and ambassador to Queen Elizabeth I of England and his brother Marcantonio, an ambassador to King Charles IX of France. The villa was added to the list of World Heritage Sites by UNESCO in 1996.

Andrea Palladio was an Italian Renaissance architect active in the Venetian Republic. Palladio, influenced by Roman and Greek architecture, primarily Vitruvius, is widely considered to be one of the most influential individuals in the history of architecture. While he designed churches and palaces, he was best known for country houses and villas. His teachings, summarized in the architectural treatise, The Four Books of Architecture, gained him wide recognition.
